Desman

The Desman project was a fun project. I enjoyed figuring out the different equations and applying them to my own Desman. Seeing the equations plugged in and watching them create something on my graph was awesome. Something that was challenging was the initial figuring-out of the equations. I used Mr. McCune's example graph in order to find the numbers that would work with my graph when I got stuck. This project was fun overall.

Lessons 8.1 - 8.3


8.1

A polygon is convex if no line that contains a side of the polygon passes through the interior of the polygon.

A polygon is concave it at least one side that contains a side of the polygon passes through the interior of the polygon

A polygon that is not convex is called concave

A polygon is equilateral is all of its sides are congruent. 
A polygon is equiangular if all of its sides are congruent. 
A polygon is regular if it is both equilateral and equiangular.

Nothing in this chapter really challenged me much. Everything was fairly easy for me.

8.2:

Polygon Interior Angle Theorem:
The sum of the measures of the interior angles of a convex polygon with N sides is (N-2) x 180 

Polygon Exterior Angle Theorem: 
The sum of the measures of the exterior angles of a convex polygon, one angle at each vertex is 360 degrees

Everything in this chapter was easy. The most confusing thing was probably the exterior angles and where in the polygon they were located.

I can remember the exterior angles by extending the sides of the polygon and making sure that each angle is facing the same direction.

8.3:


The amount of surface covered by a figure is called its area

Area of a square:
Area = Side (squared) 

Area of a rectangle:
Area = (base)x(height) 

Area of a complex polygon:
To find the area of a complex polygon, divide the polygon into smaller polygons whose areas you can find 

Nothing in this chapter was challenging for me.

Overall:

Overall, I learned the different kinds of polygons, how to find their areas, and was able to find the measure of a specific angle in a polygon, whether it was interior or exterior.


The most challenging thing overall was trying to find the exterior angles of a polygon. I wasn't sure where exactly the exterior angles were located and to which way they were facing. Once I extended the sides of the polygon, I eventually found which way the angles were supposed to face and then find out what each angle measured.

Mark 2:1-11

   In the book of Mark, Jesus comes to Capernaum to preach. The streets flooded with people so not everyone could fit in the building he preached in. Four men brought a paralyzed man to see Jesus, but they could not reach him due to the large numbers of people. The men lowered the cripple through the roof of the building Jesus was in. Jesus god the man that he had been forgiven for his sins, and commanded the man to walk out of the room, and so, he walked. 
   Something that stood out to me the most was the fact that before allowing the paralyzed man to walk, he forgave him of his sins. What the people didn't understand was the fact that sins were more crippling than a disability. Jesus freed the man from being paralyzed, but he also freed him from his sins which is more important.

7.4 - 7.6

7.4: SSS and SAS Similarity

SSS Similarity Postulate:
   If the corresponding sides of two triangles are proportionate, then the two triangles are similar.

SAS Similarity Postulate:
   If an angle of one triangle and the length of the sides that include these angles are proportionate, then the triangles are similar.

Nothing was difficult in this section

7.5: Proportions and Similar Triangles
Proportionality:
   If GP:PH = JQ:QK then GH and JK are divided proportionally 

Triangle Proportionality Theorem:
   If a line parallel to one side of a triangle intersects 
the other sides, then it divides the two sides proportionally.

Converse of the Triangle Proportionality Theorem:
   If a line divides two sides of a triangle proportionally, then it is parallel to the third side.

Midsegment Theorem:
   The segment connecting the midpoints of two sides of a triangle is
parallel to the third side and it is half as long.

Nothing in this section challenged me




7.6: Dilations

Dilation: 
   A dilation is a transformation with center C and scale factor K that maps each point P to an image point P(prime) so that P(prime) lies on CP and CP(prime) = K x CP.

   A dilation maps a figure onto a similar figure called the image.
   In a dilation, every image is similar to the original figure.

Types of Dilations:
   If the image is smaller then the original, the dilation is a reduction.
   If the image is larger than the original, the dilation is an enlargement.

Scale Factor:
   The scale factor of a dilation is the ratio of CP(prime) to CP.
   
The most challenging thing in this section was the scale factor. I learned that, once I found that CP(prime) is always over CP, the scale factor wasn't hard to figure out.


Overall:
   Overall, I thought the most challenging thing was the scale factor and how to find it. I eventually figured out that CP(prime) is over CP and from there, I could find the ratio of the scale factor.

Chapters 7.1 - 7.3

7.1: Ratios and Proportions

A ratio is a comparison of a number a and a nonzero number b using division.
    Ratios can be written in four different ways.
    Ratios are usually written in simplest form.
An equation that states two ratios are equal is called a proportion 
    In the proportion A:B = C:D, the numbers B and C are called the means, and A and D are the extremes 
In a proportion, the product of the extremes is equal to the product of the means

In this lesson, the means and extremes were the things to trip me up the most. I learned to just remember that, when set up in factor form, the means were always the bottom number of the first listed ratio and its diagonal, and the extreme was the top number of the first ratio and its diagonal.

7.2: Similar Polygons
Similarity:
Two figures that have the same shape, but not necessarily the same size are called similar
Similar Polygons:
If corresponding angles are congruent and corresponding side lengths are proportional, then the two polygons are similar polygons.
Scale Factor:
If two polygons are similar, then the ratio of the lengths of two corresponding sides is called the scale factor
Determining Similarity:
   1 Check that corresponding angles are congruent
   2 Check whether the corresponding side lengths are proportional
Perimeters of Similar Polygons Theorem:
If two polygons are similar then the ratio of their perimeters is equal to their corresponding side length

This lesson was easy for me, and I didn't really have any problems.

7.3 Angle-Angle Similarity

Angle-Angle Similarity Postulate:
If 2 angles of one triangle are congruent to 2 angles of another triangle, then the two triangles are similar


In the lesson, the angle-angle similarity was easy and I didn't really have any issues with it.

Overall, the lessons were fairly easy and the most challenging things were the means and extremes. As the lessons went on, I learned how to differentiate between the tow of them and I don't have any concerns for these lessons going forward.

Personal Postulates and Theorems

I Love my Family

Statement                            Reason
I love my family                           God loves me
God loves me                           He is a God of love
He is a God of love                           Because He is                        
    Theorem

God is my Father


Statement                           Reason
 God is my Father                           He created me
 He created me                           The Bible says so
 The Bible says so                           Its God's word
Its God's word                           It just is
     Theorem   

I Like the Color Purple
    Statement                            Reason  
I like the color purple                           I just do
       Postulate     

   The first one of the theorems in my life is something I had never really had an answer to. I never actually thought about why I loved my family, despite the fact that they loved me. I found out that the reason I love my family is because God loves me. The second one of my theorems, is the fact that God is my Father. I actually knew why He was my Father, that being He created me and the Bible, His word, said so. The postulate I came up with is simple. I like the color purple because I just do. It looks terrible when I wear it as clothing, I never use it in any of my art pieces for school, and there are so many different colors for me to like. I like the color purple, and I can't prove why, so its a postulate. 
   In learning about personal postulates and theorems, I also realize that there are reasons for almost everything, big or small. Going forward, I will pay attention to my own postulates and theorems, appreciating how they affect me and my beliefs. I will also recognize other people's personal beliefs and respect them, knowing there is either a reason to them, or because they just are.

Hour of Code

During class we were assigned to lear how to use codes to control what happened on our computer screens We were given the option to use either a "Frozen" themed template or and "Angry Birds" template. I chose Frozen, and got to make Elsa and Ana move the way I wanted to with the help of the Hour of Code steps. I really enjoyed this because I got to see how some of the electronic things I use everyday were programed to do their jobs. Something that was challenging was trying to figure out how many degrees the figure was supposed to turn to make the desired shape. I learned how to make simple commands on a computer and make something interact using those same commands. Something that was surprising was the fact that I eventually made around 36 different codes when playing a simple game! One code I used to make a cool shape that looks like a snowflake is listed below, followed by the finished product!

for (var count2 = 0; count2 < 10; count2++) {
  for (var count = 0; count < 4; count++) {
    moveForward(100);
    turnRight(90);
  }
  turnRight(36);
}
This assignment was very fun and a great learning opportunity!
