Solution:

Based on the size of angles, triangles can either be an acute triangle, a right triangle, or an obtuse triangle.

An acute triangle is one in which all of its three interior angles are less than 90°.

A right triangle has one of its interior angles to be equal to 90°.

An obtuse triangle is one in which one of its interior angles is greater than 90° .

Given that a triangle has its angle measurements to be

[tex]151\degree,\text{ 28}\degree,\text{ 1}\degree[/tex]

We see that one of its angles is greater than 90°. This implies that the triangle is an obtuse triangle.
