Understanding Pythagoras Theorem

The video explains Pythagoras Theorem, focusing on a proof by Einstein. It begins with a basic understanding of the theorem, using squares on the sides of a right triangle to demonstrate the relationship between the areas. The video then explores an alternative proof using semicircles, illustrating the theorem's general applicability. It further generalizes the proof by constructing similar shapes on the triangle's edges. Finally, the video uses similar triangles to complete the proof, emphasizing the congruence of the triangles involved.

What is the basic equation of Pythagoras Theorem in terms of the lengths of the sides?

• c^2 = a^2 - b^2

• b^2 = a^2 + c^2

• a^2 = b^2 + c^2

• a^2 + b^2 = c^2
