if angle pqr=1 1/2 right angles find the reflex angle pqr

Answer 1

The reflex angle of a given angle is the larger between the angle itself, and the angle formed by 360 minus the angle.

For example, the reflex angle of 150° is 360-150=210°.

Since angle pqr=1 1/2 right angles
= 135°.
Calculate the reflex angle of 135° by subtracting 135° from 360°.
