Solution

Concept- If one of the angles of a triangle is an Obtuse angle, the triangle is called an obtuse-angled triangle or simply an obtuse triangle.
According to the question, in the given triangle $△$ PQR, given that $∠ Q = 135 °$
Hence, $∠$ Q is an Obtuse angle.
Therefore, the given triangle is an Obtuse-angled triangle.
