Question
Draw a line segment PQ = 6 cm. Mark a point A in PQ so that AP = 2 cm. At point A, construct angle QAR = 60°.

Answer
Steps of Construction: (i) Draw a line segment $P Q=6 cm$. (ii) Mark a point $A$ on $P Q$ so that $A P=2 cm$. (iii) With centre $A$ and some suitable radius draw an arc meeting $A Q$ at $C$. (iv) With centre $C$ and with the same radius, cut $\operatorname{arc} C B$. (v) Join $A B$ and produce it to $R$. Then $\angle QAR =60^{\circ}$
