Answer 1

Answer:

Steps of Construction :

(i) Draw a line segment BC.

(ii) With centre B and some suitable radius, draw an arc meeting BC at P.

(iii) With centre P and with same radius, cut arcs PQ and QR.

(iv) Join BR and produce it to A.

Then ∠ABC = 120°

(v) With centres P and R, draw two arcs intersecting each other at S.

(vi) Join BS and produce it to D. BD is the bisector of ∠ABC.

On measuring each angle, it is of 60° each. Yes, both angles are equal in measure.
