Question

what kind of triangle has sides that are 16 21 and 32

Answer 1

To help you get started, several descriptors of triangles are isosceles, acute, right and obtuse. I'd suggest you start by determining whether there is any definite mathematical relationship between 16 and 21 on the left and 32 on the right.

Answer 2

acute triangle

Answer 3

the are all less than 90 , but not greater than 180.

Answer 4

That's a good descriptor of an acute triangle, but I'm wondering how you determined that all the angles are less than 90 but not greater than 180 degrees.
