A triangle has sides with length of 12 miles 16 miles 20 miles

Is it a right triangle

Yes! This is a right triangle.

Step-by-step explanation:

To solve this problem, you need to use the Pythagorean Theorem, which is: . In this equation, "A" represents the smallest length, "B" represents the next smallest length, and "C" represents the largest length. If a triangle is a right triangle, then the A squared + B squared equals C squared.

In this equation:

A = 12

B = 16

C = 20

 1. Insert the values:

               2. Simplify:

                                   , and , so this is a right triangle.
