Question

Construct a △PQR such that PQ = 6cm, ∠P=45⁰ and ∠Q=60⁰.
Also, find the measure of ∠R.

Answer 1

Steps of Construction:
1. Draw a line segment PQ=6 cm
2. At P, draw a ray making an angle of 45⁰
3. At Q, draw another ray making an angle of 60⁰.
4. Name the point of intersection of rays as R.

△PQR is the required triangle.

On measuring ∠R, it must come out to be 75⁰.
