Refer to pages 3-5 for exercise 10.1 in the PDF

1. Draw a line, say $AB$, take a point $C$ outside it. Through $C$, draw a line parallel to $AB$ using ruler and compasses only.

Ans: To construct: A line parallel to given line using only ruler and compasses.

Steps of construction:

(a) Draw a line-segment $AB$ and mark a point $C$ outside $AB$.

(b) Take any point $D$ on $AB$ and join $C$ to $D$.

(c) With $D$ as centre and take convenient radius, draw an arc cutting $AB$ at $E$ and $CD$ at $F$.

(d) With $C$ as centre and same radius as in step 3, draw an arc $GH$ cutting $CD$ at $I$.

(e) With the same arc $EF$, draw the equal arc cutting $GH$ at $J$.

(f) Join $JC$ to draw a line $l$.

This is the required line $AB\parallel l$.

2. Draw a line $l$. Draw a perpendicular to $l$ at any point on $l$. On this perpendicular choose a point $X$, $4$ cm away from $l$. Through $X$, draw a line $m$ parallel to $l$.

Ans: To construct: A line is to be drawn which is parallel to a given line and when a perpendicular line is also given.

Steps of construction:

(a) Draw a line $l$ and mark a point $P$ on it.

(b) From point $P$, draw a perpendicular line $n$.

(c) Take $PX = 4$ cm on line $n$.

(d) At point $X$, again construct a perpendicular line $m$.

The required construction is as above.

3. Let $l$  be a line and $P$ be a point not on $l$. Through $P$, draw a line m parallel to $l$. Now join $P$ to any point $Q$ on $l$. Choose any other point $R$ on $m$. Through $R$, draw a line parallel to $PQ$. Let this meet $l$ at S. What shape do the two sets of parallel lines enclose?

Ans: To construct: A pair of parallel lines that intersect other part of parallel lines.

Steps of construction:

(a) Draw a line $l$ and mark a point $P$ which is not on $l$.

(b) Take point $Q$ on line $l$ and join the points $P$ and $Q$.

(c) Construct equal angles at point $P$ such that $\angle Q = \angle P$.

(d) Increase the line at $P$ to obtain line $m$.

(e) Similarly, take a point $R$ on line $m$, then at point $R$, draw angles such that $\angle P = \angle R$.

(f) Extended line at $R$ which intersects at $S$ on line $l$. Draw line $RS$.

Thus, the two sets of parallel lines enclose a parallelogram $PQRS$.
