Classify the following triangle as acute, right or obtuse. a triangle with side lengths of 12 in, 15 in, and 20 in. explain why.

I think its acute because first of all, when you have a right triangle, at least two of the sides have to be even. Secondly when I actually put the triangle together, the triangle had no sides that were greater than 90°, so then that rules out obtuse, so than that has to be acute because all angles are shorter than 90°

Aline graph should be used

Idon’t know what the answer is i wish i could
