Question
Construct traingle ABC, when: AB = 7 cm, ∠B = 120° and ∠A = 30°. Measure AC and BC.
Solution
Steps of Construction:
(1) Draw a line segment AB = 7 cm
(2) At A construct an angle ∠A = 30°.
(3) At C construct an angle ∠C = 45°.
(4) AE and BD intersect each other at C.
(5) ∴ ∆ABC is the required triangle.
(6) On measuring length of AC = 12cm and BC = 7 cm respectively.
