Question

A triangle has sides with lengths of 16 millimeters, 20 millimeters, and 25 millimeters. Is it a

right triangle?

Answer 1

No

Explanation:

If it is a right triangle, then the Pythagorean theorem must work.

a^2 + b^2 = c^2 (a and b are the shorter sides and c is the longest)

16^2 + 20^2 = 25^2

256 + 400 = 625

656 = 625

This is not true

Hope this helps!
