  $△PQS$ is an obtuse triangle.

Explanation of Solution

Given information:

Given conditions:

  $△PQS$ As acute, equiangular, obtuse or right.

  $△PQS$ is as follows:

  

A triangle is acute if all angles are acute.

A triangle is right if one angle is right.

A triangle is obtuse if one angle is obtuse.

Since, one angle of the triangle is of measure $125$ , the angle is an obtuse angle. So, the triangle is an obtuse triangle, because one angle of the triangle is an obtuse angle.
