Pythagoras theorem explanation 2

The following may also help you remember the Pythagoras theorem formula.

Three squares placed together forming a triangle in the middle

The sum of the squares `A+B` are exactly the same size as square `C`

The sum of the first 2 squares are exactly the same size as the third square

We can also show this more explicit by drawing the same problem with cubes.

The same diagram drawn with cubes to make things more obvious

`a^2+b^2=c^2`

Proved by

`3times3` `+` `4times4` `=` `5times5`
`9` `+` `16` `=` `25`
    `25` `=` `25`

They call this a three, four, five triangle and it only works with right angled triangles.
