Given that triangle LMN has side lengths of 20 inches, 10 inches, and 12 inches, prove triangle LMN is a right triangle. Explain
il63 [147K]

Answer:

It is not a right triangle. The hypotenuse is the biggest side so if you apply the Pythagorean Theorem formula it does not work.

Step-by-step explanation:

A² + B² = C² -------> 10² + 12²=20² --------> 100 + 144 = 400 ---> 244 = 400
