We can check this by seeing if Pythagorean's theorem applies. The longest side is the hypotenuse, so let's see if this is true:
![60^2+63^2 = 87^2](https://tex.z-dn.net/?f=60%5E2%2B63%5E2%20%3D%2087%5E2)
![7569 = 7569](https://tex.z-dn.net/?f=7569%20%3D%207569)
This is, indeed correct, thus, this
<em>is </em><em>
a right triangle.</em>
