Show transcript
A visual approach can help you understand the structure behind Pythagoras' theorem.
There is a difference between proof and demonstration.
A demonstration would be showing Pythagoras' theorem works for specific right-angled triangles.
A proof is generalised i.e. using four congruent triangles arranged in a particular way inside a square.
The sum of the squares of the two shorter sides equals the square of the longest side.
