Answer:
Yes!
Step-by-step explanation:
We know that right triangles follow the Pythagorean Theorem, where
[tex]a^{2} + b^{2} = c^{2}[/tex]
So we will put our side lengths into this formula, keeping in mind that c = the hypotenuse, which is the longest side. a and b are fairly arbitrary.
[tex]16^{2} + 63^{2} = 65^{2}[/tex]
If this works, we know it's a right triangle.
256 + 3969 = 4225
4225 = 4225
It worked! It's a right triangle!!
