squared sides add up every time

The square of the longest side is equal to the
squares of the other two sides added together
This has to be one of the most amazing patterns you’ll discover
in geometry. Whenever you have a right triangle, if you draw a
square on the longest side, its area is exactly equal to the squares
you could draw on the other two sides.
This works for EVERY
right triangle you could
draw.
