PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!

A triangle has sides with lengths of 10 inches, 10 inches, and 15 inches. Is it a right triangle?

Yes or no?

Answer 1

no, this is not a right triangle. with pythagorean's theorem, a^2 + b^2 = c^2, but in this case, 10^2 + 10^2 ≠ 15^2 (100+100≠225). this is not a right triangle.

Answer 2

Answer:

No

Step-by-step explanation:

No because the side would have to be multiplea of 3, 4 and 5 for there to be a right angle
