### Right Triangle Problem

I have a right triangle with side lengths 4 and 5;

I need to know what’s missing, but first I must decide

:

Is the missing side a leg or is it hypotenuse?

I know I’ll use the formula, the question is, “Which
use?”

When given sides are legs, I’ll square and find the
sum.

The longest side I then will know:____________________

If 5 is the hypotenuse, subtraction is the key.

I’ll square, subtract, and take the root; the answer
now is ______________.
