Special angles Sentry theorem
... 4.1. Show that a regular dodecagon can be cut into pieces that are all regular polygons, which need not all have the same number of sides. 4.2. Mark P inside square ABCD, so that triangle ABP is equilateral. Let Q be the intersection of BP with diagonal AC. Triangle CP Q looks isosceles. Is this act ...
