It states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side, called the hypotenuse. This theorem is named after the Greek mathematician Pythagoras, who lived in the 6th century BC and is considered one of the founders of mathematics.

In this visual derivation, we explore how a / sin A = b / sin B = c / sin C emerges naturally from geometry. This reel breaks down the concept using animated diagrams, triangle projections, and clear geometric reasoning — perfect for students studying Class
