The Pythagorean Theorem is one that proves a right triangle is truly a right triangle. By plugging in our sides, we can determine whether or not a triangle is a right triangle. We know that the pythagorean theorem is written as follows:
+
=
After drawing the representation of the triangle, and using side km = 16, we can use the process of elimination to determine which answer choice will give us a balanced equation (both sides of the equation are equal to each other). When we plug lm = 12 and nm = 9 into our equation, we have the following:
= 9 * 16
144 = 144
So, the lengths that would make triangle klm a right triangle are lm = 12 and nm = 9.
