Areas and Perimeters of Regular Polygons (visual proof)

This is a short, animated visual proof demonstrating that the area of the regular 2n-gon inscribed in a circle of radius r is equal to one-half the product of r and the perimeter of the regular n-gon inscribed in the same circle. We finish with a bonus proof that the area of a circle is one-half the product of its radius and its circumference. #math​ #geometry #mtbos​ #manim​ #animation​ #theorem​ #pww​ #proofwithoutwords​ #visualproof​ #proof​ #iteachmath #polygons #regularpolygon #circlearea #area #perimeter #mathshorts​ #mathvideo​ This animation is based on a visual proof by Roger B.
