Question

Construct traingle ABC, when : AB = BC = CA = 4.5 cm. Measure all the angles of the triangle. Are they equal?

Answer 1

Steps of Construction:

(1) Draw a line AB = 4.5 cm.

(2) Using compasses and taking BC as centre, draw an arc of 4.5 cm radius.

(3) With AC as centre, draw an arc of 4-5 cm radius, which cuts the previous arc at C.

(4) Join AC and BC.

(5) Measurement, ∠A = ∠B = ∠C = 60°.
