Classify the following curves as

(i) Open or

(ii) Closed.

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

(a) Point P lies on.

(b) and intersect at M.

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

(d) and meet at O.

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

(a) Q, M, O, N, and P are the points on the line MN.

(b) M, O, N are points on a line segment MN.

(c) M and N are end points of line segment MN.

(d) O and N are end points of line segment OP.

(e) M is one of the end points of line segment QO.

(f) M is point on ray OP.

(g) is different from .

(h) is same as .

(i) is not opposite to .

(j) O is not an initial point of .

(k) N is the initial point of and

Draw rough diagrams to illustrate the following:

(a) Open curve

(b) Closed curve.

Draw any polygon and shade its interior.
