Answer
No
$24^{2}$+$8^{2}$$\ne$$25^{2}$
Work Step by Step
The Pythagorean Theorem says that $(leg_{1}) ^{2}$+$(leg_{2})^{2}$=$hypotenuse^{2}$. If this is true, then a triangle is a right triangle.
This formula is more commonly referred to as $a^{2}$+$b^{2}$=$c^{2}$
You are given the lengths of the legs as 24 and 8. You are given the length of the hypotenuse as 25. Substitute 24 in for a, 8 in for b, and 25 in for c.
$a^{2}$+$b^{2}$=$c^{2}$
$24^{2}$+$8^{2}$=$25^{2}$
576+64=625
640$\ne$725
