Question

Construct a triangle ABC, given that the radius of the circumcircle of triangle ABC is 3.5 cm, ∠ BCA = 45° and ∠ BAC = 60°.

Answer 1

Steps of construction:

(i) Draw a circle with radius = 3.5 cm
(ii) Again make ∠ BOC = 120°
(iii) Draw diameter BOD and construct ∠ BOA = 90°
(iv) Join AB, AC, and BC. Then ∠ ABC is the required triangle.
