"Webband surprising result to any polygon that circumscribes a circle (Theorem 6). A key ingredient of the proof is a link to Archimedes' striking discovery concerning the area of a circular disk [4, p. 91], which for our purposes we prefer to state as follows: Theorem 1 (Archimedes). The area of a circular disk is equal to the product of its " - Simple circle theorems

WebbSo I wanted to create an animation that drew a circle on the left and a square on the right. Then, they would get together at the center of the screen and create a triangle. At last, this triangle was supposed to rotate. I thought of actually creating two different triangles which would overlap, so as to only look like one triangle. WebbCircle Theorems Theorems.
