Question

Construct triangle ABC such that AB =7cm,AC=5cm,and angle BAC=60°.Measure BC.​

Answer 1

(i) Steps of Construction :

(i) Draw a line segment AB = 7 cm.

(ii) At B, draw a ray making an angle of 60° and cut off BC = 5 cm

(iii) Join AC,

∆ABC is the required triangle.

(ii) Steps of Construction :

(i) Draw a line segment BC = 6 cm.

(ii) At C, draw a ray making an angle of 75° and cut off CA = 5.7 cm.

(iii) Join AB

∆ ABC is the required triangle

(iii) Steps of Construction :

(i) Draw a line segment AB = 6.5 cm

(ii) At A, draw a ray making an angle of 45° and cut off AC = 5.8 cm

(iii) Join CB.

∆ ABC is the required triangle.
