∠ABC = 60°

Open in App

Solution

Steps of construction:

(i) Draw ∠ABC = 60°.

(ii) With B as center and a convenient radius, draw arcs which cut AB and AC at F and E respectively.

(iii) With E and F as centers, draw arcs with a convenient radius, cutting each other at P

Join BP.

Thus, BP is the required bisector of ∠ABC.

On measuring, it is observed that ∠ABD = ∠DBC = 30.
