Law Of Cosines I (visual proof)

This is a short, animated visual proof of the Law of Cosines using Thales triangle theorem and the intersecting chord theorem. This theorem relates the side of a triangle with the other two sides and the angle between those two sides. #mathshorts #mathvideo #math #trigonometry #lawofcosines #triangle #manim #animation #theorem #pww #proofwithoutwords #visualproof #proof #circle #thalestheorem #intersecting chords

This animation is based on a proof due to Sidney H. Kung from the December 1990 issue of Mathematics Magazine (https://doi.org/10.2307/2690911) page 342.
