Question

Draw a circle 4cm and construct a triangle on it measures 50°,60°,70°​

Answer 1

(1) Draw a circle with centre O and having radius 4cm

(2) To make the three points A,B,C in the circle, join A to the centre of the circle O.

(3) If m∠ABC is to be 50°,m∠AOC should be 100°.

(4) If m∠BAC is to be 60°, m∠BOC should be 120°.

(5) Join the points B and C such that m∠AOC = 100° and m∠BOC=120°

Thus,

△ABC is the required triangle.
