Question

A triangle has side lengths of 10 inches, 24 inches, and 26 inches. is this a right triangle?

Answer 1

To check it we can use Pythagorean theorem.
$a^2+b^2=c^2$, where c is the longest side.
Lets check it
Assume that a=10 and b= 24
$10^2+24^2=100+576=676$
Now lets compare with c^2=676
Its equal, so its right triangle.
