Question

A triangle has sides with lengths of 4 yards, 6 yards, and 7 yards. Is it a right triangle?

Answer 1

For this question we will need to use the Pythagorean theorem:

a^2 + b^2 = c^2

4^2 + 6 ^2 = 7^2

16 + 36 = 49

52 ≠ 49

Since the Pythagorean theorem doesn’t seem to work, we can conclude that the triangle is NOT a right triangle.

Have a good day ^^
