If l is any given line and P is any point not lying on l, then the number of parallel lines that can be drawn through P, parallel to l would be:
Question 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?
