Question

Draw a line $l$. Draw a line $n$ which is parallel to line $m$ at a distance of $4\text{cm}$ from it.

Answer 1

Steps to construct:
a) Draw line $l$.
b) Take two points $A$ and $B$ on the line $l$.
c) Draw perpendicular lines above to the line $l$ from points $A$ and $B$ with a distance of $4\text{cm}$, and mark that points as $P$ and $Q$.
d) Join line $PQ$.
e) Line $PQ$ is a line parallel to the line $l$ at a distance $4\text{cm}$. Hence, the required line is obtained.
