The perimeter is the sum of the measures of the sides, so:



Solve for , then calculate , , and .

Label the two smaller values and , then the largest .

Calculate . If that is equal to it is a right triangle, otherwise not.

OR:

Calculate and see if it is equal to . If it is, it is a right triangle. Otherwise not.
