Classify the triangle with angles with measures 33, 90, and 57 as acute, right, or obtuse.

We know that

A right triangle is a triangle in which one angle is a right angle

and

a right angle is equal to 90°

therefore

the answer is

A right triangle

This triangle is classified as a right triangle because it contains one right angle (90 degrees).

An obtuse triangle is given that classification when one of the angles is greater than 90 degrees.

An acute triangle is any triangle that has all 3 angles less than 90 degrees.
