Question

A triangle has side lengths of 34 in, 28 in, and 42 in. Is the triangle acute, obtuse, or right.

Answer 1

Compare a^2 + b^2 to c^2
If they're equal, it's right (Pythagorean thm)
If c^2 is greater than a^2 +b^2, it's obtuse
If c^2 is less than a^2 +b^2, it's acute

Answer 2

let a = length of shortest side and b = length of next shortest side.

then if \(a^2+b^2=c^2\) it's a right triangle
if \(a^2+b^2<c^2\) it's an obtuse triangle
if \(a^2+b^2>c^2\) it's an acute triangle
