(a) A line containing E = AE or FE
(b) A line passing through A = AE or DE
(c) A line on which O lies = CO or OC
(d) Two pairs of intersecting lines are: AD, CO andAE, FE
Draw a rough figure and label suitably in each of the following cases:
(a) Point P lies on AB.
(b) XY s ruu and PQ s ruu intersect at M.
(c) Line l contains E and F but not D.
(d) OP s ruu and OQ s ruu meet at O.
