Draw two parallel lines using a ruler, and verify whether they are parallel to each other by construction.

The steps to construct a $∆\mathrm{P}\mathrm{Q}\mathrm{R}$ with $\mathrm{Q}\mathrm{R}=4 \mathrm{c}\mathrm{m}, \mathrm{P}\mathrm{Q}=5 \mathrm{c}\mathrm{m} \mathrm{a}\mathrm{n}\mathrm{d} \mathrm{Q}\mathrm{R}=5.5 \mathrm{c}\mathrm{m}$ are given below in a jumbled order. Arrange the steps in the correct order.

(a) With $\mathrm{Q}$ as centre and a radius equals to $5 \mathrm{cm}$, draw an arc.

(b) Draw a line segment $\mathrm{QR}$ of $4 \mathrm{cm}$.

(c) Join $\mathrm{P}$ and $\mathrm{Q}$, and $\mathrm{P}$ and $\mathrm{R}$. $△\mathrm{PQR}$ is the required triangle.

(d) With $\mathrm{R}$ as the centre and a radius of $5.5 \mathrm{cm}$, draw another arc intersecting the previous arc at $\mathrm{P}$.

The steps to construct a $∆\mathrm{PQR}$ in which $\mathrm{PQ}=4 \mathrm{cm}, \mathrm{QR}=6 \mathrm{cm}$ and $\mathrm{\angle }\mathrm{PQR}=60°$are given below in a jumbled order. Arrange the steps in the correct order.

(a) With $\mathrm{Q}$ as the centre and a radius of $4 \mathrm{cm}$, draw an arc on ray $\mathrm{QX}$. Label the point of intersection as $\mathrm{P}$.

(b) Draw a line segment $\mathrm{QR}$ of length $6 \mathrm{cm}$.

(c) With the help of compasses, construct an angle $\angle \mathrm{XQR}$ of measure $60°$ at point $\mathrm{Q}$.

(d) Join points $\mathrm{P}$ and $\mathrm{R}$. $△\mathrm{PQR}$ is the required triangle.
