Question

Construct an isosceles triangle in which the length of each of equal sides is $65$ cm and the angle between them is ${110}^{\circ }$.

Answer 1

(a) Draw a line segment $QR=6.5$ cm.

(b) At point $Q$, draw an angle of ${110}^{\circ }$ with the

help of protractor, i.e., $\angle YQR={110}^{\circ }$

(c) Taking $Q$ as centre, draw an arc with radius

$6.5$ cm, which cuts $QY$ at point $P$.

(d) Join $PR$.

It is the required isosceles triangle $PQR$.
