Judge whether the triangle whose three sides are 2n ^ 2 + 2n, 2n + 1, 2n ^ 2 + 2n + 1 is a right triangle Judge whether the triangle whose three sides are 2n ^ 2 + 2n, 2n + 1, 2n ^ 2 + 2n + 1 (n is greater than 0) is a right triangle Remember to prove which is the hypotenuse! To prove why that's a hypotenuse

The last one is the biggest, so it's probably beveled
(2n^2+2n)^2+(2n+1)^2=(2n^2+2n)^2+4n^2+4n+1
=(2n^2+2n)^2+2(2n^2+2n)+1
=(2n^2+2n+1)^2
It's a right triangle
