To Construct a Triangle when Two of its Sides and the Included Angles are given



To construct a triangle when two of its sides and the included angles are given, let’s follow the examples.



1. Draw a triangle ABC in which AB = 5 cm, BC= 7 cm, and ∠B = 75°.

Steps of Construction:

(i) Draw a line segment AB = 5 cm.

(ii) Make ∠ ABC = 75°.

(iii) Cut of BC = 7 cm.

(iv) Join AC.

Therefore, ∆ ABC is the required triangle.



2. Draw a triangle ABC in which AB = 4.5 cm, BC = 6 cm, and ∠B = 80°.

Steps of Construction:

(i) Draw a line segment AB = 4.5 cm.

(ii) Make ∠ ABC = 80°.

(iii) Cut of BC = 6 cm.

(iv) Join AC.

Therefore, ∆ ABC is the required triangle.
