Answer :

(i) Draw a line AB.

(ii) Take any point R on it.

(iii) Join the given point C to R and mark \(\angle \)CRA.

(iv) Mark \(\angle CRA = \angle QCB \) at C and produce to both side.

(v) PQ is the required line.

- Q.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.
- Q.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?
