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.
Answer :

(i) Draw a given line l and take any point P on it.
(ii) Draw a perpendicular line at P to the line l such that PX = 4 cm.
(iii) Draw \(\angle \)2 = \(\angle \)1 i.e. 90° at PX and produce the line both sides.
(iv) m is the required line parallel to l through X. Using Properties of Alternate Angles
