Question

Bisect the given angles and measure the bisected angles in the following:

∠LMN = 90°

Answer 1

(i) Draw ∠LMN = 90°.

(ii) With M as center and a convenient radius, draw arcs which cut ML and MN at Q and R respectively.

(v) With Q and R as centers, draw arcs with a convenient radius, cutting each other at P. Join MP.

Thus, MP is the required bisector of ∠LMN.

On measuring, it is observed that ∠LMP = ∠PMN = 45°.
