Answer 2

Given: AB = 4.5 cm, Angle A = 80°, Angle B = 30°

Required: To construct a triangle ABC, such that AB = 4.5 cm,Angle A = 80°, Angle B = 30°

Steps of Construction:

Step 1: Since we have one side i.e AB = 4.5 cm so take it as base.

Step 2: Now taking A as center draw a 90° angle using compass and then using protractor make 80° angle (or use only protractor to make 80°)

Step 3: Now taking B as center draw 60° angle and bisect to get 30° angle.

Step 4: Join both the lines such that both intersect at point C.

Hence, triangle ABC can be constructed.
