What is Hippocrates theorem about the circle?

Hippocrates' theorem states that if a right triangle is inscribed in a circle, the area of the circle can be expressed as the sum of the areas of the squares constructed on the two legs of the triangle. This theorem illustrates a geometric relationship between the triangle and the circle, highlighting that the area of the circle (when a right triangle is inscribed) equals the combined areas of the squares on its two shorter sides. It serves as an early insight into the connection between geometry and area.
