### NCERT solutions for Class 7 Maths Chapter 10 Practical GeometryExercise 10.1 [Page 196]

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

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.

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?
