Chapter 10: Practical Geometry Exercise 10.10 solutions [Page 196]

Ex. 10.10 | Q 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

Ex. 10.10 | Q 2 | Page 196

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.

Ex. 10.10 | Q 3 | Page 196

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?
