SOLUTION: how do you find the lenght of the diagonal?

You can put this solution on YOUR website!
If we have a right triangle, (a triangle with a right angle) we can use Pythagoreans theorem:

Where a and b are the legs of the triangle and c is the hypotenuse (the diagonal). So if a triangle has legs of 3 and 4 we plug them into Pythagoreans theorem






So if I have legs of 3 and 4, I will have a diagonal of 5.
