Question

Construct traingle ABC, when : AB = 5.4 cm, ∠A = 30° and ∠B = 90°. Measure ∠C and side BC.

Answer 1

Steps of Construction:

(1) Draw a line segment AB = 5.4 cm.

(2) At A construct an angle ∠A = 30°.

(3) At B construct an angle ∠B = 90°.

(4) AD and BE intersect each other at C.

(5) ∴ ∆ABC is the required triangle.

(6) On measuring ∠C = 60° side BC = 31 cm.
