Geometry

[Butter]

Mathematically Describe the design.( For shapes:Lines of symmetry, Angles, What shape it is, How you can prove that it is that shape,Rotational Symmetry, Parallel Lines, For Bisectors: what it is bisecting, what is the angle, what is the length of the line that its bisecting?) I got down the answers but I am unsure if I did them all correct. For example, I measured an angle is was 90 degrees then I measured it again it was 85 degrees. Please help. Ignore the black.

To describe this entire design in words is quite a task. And helping you is not easy, both because it is very hard to read the numbers, and because it is not clear whether those are numbers you added to the problem or numbers given by the problem itself. If we ignore the margins, what I am seeing in the center is a large dodedacgon, with its inner boundary formed by alternating blue quadrilaterals and red triangles. The sides of the quadrilaterals opposite the boundary of the dodecagon form a hexagon. I think I'd start by showing that these basic shapes are all regular (if they are). That is, are the triangles equilateral, are the quadrilaterals squares, etc. Because you are asked to PROVE your description is correct, using a protractor to measure angles is irrelevant.
