Use the figure to name :

(a) Line containing point E :

(b) Line passing through A :

(c) Line on which O lies : (or) BO

(d) Two pairs of intersecting lines : (or) AE, EF

How many lines can pass through (a) one given point? (b) two given points?

(a) Infinitely lines can pass through a given points.

(b) Only line can pass through two given points.

Draw a rough figure and label suitably in each of the following cases:

(a) Point P lies on AB.

(b) XY and PQ intersect at M.

(c) Line l contains E and F but not D

(d) OP and OQ meet at O.

Consider the following figure of line MN . Say whether following statements are true or false in context of the given figure.

Instruction

Q, M, O, N, P are points on the line MN
M, O, N are points on a line segment MN
M and N are end points of line segment MN
O and N are end points of line segment OP
M is one of the end points of line segment QO
M is point on ray OP
Ray OP is different from ray QP
Ray OP is same as way OM
Ray OM is not opposite to ray OP
O is not an initial point of OP
N is the initial point of NP and NM
True
False
