GeomeTREE (octahedron)

A polyhedron is a solid shape with 6 plane sides. The way a polyhedron and a polygon are related, is that a polygon is made up of 3 or more sides, all connected at the endpoints with congruent vertices. A polyhedron is made of 6 or more polygons. For our geomeTREE, I made an octahedron. The shape consists of 8 triangles in 2 groups of 4 triangles each. These four triangles were formed into a pyramid shape and placed base to base with the other group of 4, also formed into a pyramid. The color palate in this shape included dark blue, light yellow, rose red, and dark green. The vertices of the ornament were where each triangle made a point with the others, bound by tape. all of the sides were intersected where the different triangles met. None of the planes were parallel; however, I found the triangles to form pyramids.

Reflection:
I worked on my own for this assignment and spent a class period and a half cutting the triangles out and trying to figure out how everything would fit, and then an additional 30 minutes of finally making the little polygons into the octahedron! I learned what a polyhedron was, and that the octahedron was not made out of octagons, but rather 8 triangles. I was challenged by the actual forming of the octahedron and how the triangles could make a 3 dimensional shape. I really enjoyed the in class time, cutting the triangles out of colorful paper, listening to the Frozen soundtrack, and talking with friends while working. If I had anything to change, it would be to make the shapes due before out test and before the weekend, though my class was the only group that faced this problem.
