Question

construct <ABC=120° and bisect it.​

Answer 1

Answer:

Draw an angle of ∠AOB of 120°.

Draw an arc from point O. This arc will cut the ray OA at any point C and ray OB at any point D.

Draw two arcs of the same radii from the points C and D as centres.

Join the point O to the point M by a ray OM. ...

m∠AOM = m∠BOM =

Answer 2

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.
