Maias Geometric art

My geometric art is mostly made up of triangles. I have 4 acute angles, 1 obtuse angle, 2 reflex angles and 1 straight angle. First we did a draft of our picture. It couldn't be made using too many circles or there wouldn't be any angles. Then we chose where to place our angles. We only measured the angles with a protractor once we had started our good copy because once we enlarged it the angles would change. This is my finished product.
