Question 1:

Draw a line l. Take a point A outside the line. Through point A draw a line parallel to line l.

ANSWER:

Steps of construction :

(1) Draw a line l. Take a point A outside the line l.

(2) Draw a segment AM ⊥ line l.

(3) Take another point N on line l.

(4) Draw a segment NB ⊥ line l, such that l(NB) = l(MA).

(5) Draw a line m passing through the points A and B.

Hence, the line m is the required line that passes through point A andB.
