Construct a △PQR such that ∠P=30∘,∠Q=60∘ and PQ=10 cm.
If following are the steps of construction, then answer the following question:
Which of the following is the first step of construction?
Steps of Construction:Step 1. At P, draw a ray making an angle of 30∘.
Step 2. At Q, draw another ray making an angle of 60∘ which intersects the first ray at R. Thus, △PQR is the required triangle.
Step 3. Draw a line segment PQ=10 cm.
