Question

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

∠PQR = 110°

Answer 1

Steps of construction:

(i) Draw ∠PQR= 110°.

(ii) With Q as center and a convenient radius, draw arcs which cut PQ and QR at N and M respectively.

(iii) With M and N as centers, draw arcs with a convenient radius, cutting each other at H. Join QH.

Thus, QH is the required bisector of ∠PQR.

On measuring, it is observed that ∠PQH = ∠HQR = 55°.
