Maths - Pythagoras Theorem Explained

This is a nice video explaining the concept of Pythagoras Theorem.

Years ago, a man named Pythagoras found an amazing fact about triangles:

If the triangle had a right angle (90°) ...... and you made a square on each of the three sides, then ...... 
the biggest square had the exact same area as the other two squares put together!


  • c is the longest side of the triangle
  • a and b are the other two sides


The longest side of the triangle is called the "hypotenuse", so the formal definition:
In a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other 2 sides.

This video also explains the formula:
(a+b)²= a² + 2ab + b²
