Question

A triangle has sides with lengths of 10 yards, 12 yards, and 14 yards. Is it a right triangle?

yes or no?

Answer 1

No

Explanation:

The sum of the squares of the lengths of the two shorter sides is
`10^2+12^2=244`.

The square of the length of the largest side is
`14^2=196`.

Because these two values are not equal, the side lengths do not satisfy the Pythagorean theorem. Therefore, the triangle is not a right triangle.

Answer 2

Yes it can be a right triangle even if it has 3 different lengths
