Question

Construct the triangle MRB in which RB = 5.2 cm. ∠R = 30°, ∠B = 120° and measure ∠M.

Answer 1

Construction of ΔMRB, where RB = 5.2 cm, and .

Steps of construction:

(i) Draw RB = 5.2 cm.

(ii) Using a protractor at R and B, construct and.

Let them meet at M.

Thus, triangle MRB is the required triangle.

On measuring, it is observed that ∠M = 30°
