No, we cannot draw a line on the surface of a sphere which lies wholly on it.

Question no – (4)

Solution :

(a) Infinite lines can draw through a point.

(b) Only one line can draw through two points.

Question no – (5)

Solution :

There lines can be draw through three non collinear points.

Question no – (6)

Solution :

(A) Maximum number of points of intersection of three lines in a plane is 3

(B) Minimum number of points of intersection of three lines in a plane is 0

Question no – (7)

Solution :

(i) Four examples of intersecting lines are –

(a) A pair of scissors

(b) plus

(c) The letter X of English alphabet.

(ii) Four examples of Parallel lines are –

(a) Truck of a railway.

(b) opposite line of a rectangle field.

(c) opposite edge of a cube.

Question no – (8)

Solution :

Collinear points :

Three or more points in a plane which lie or the same line are called Collinear points.

Only one line can be drawn through three collinear points.

Question no – (9)

Solution :

Concurrent lines :

Three or more lines in a plane are said to be concurrent if all them pass through the same point.

AD, BE and CF are in concurrent.

H is their point of concurrence.

Question no – (10)

Solution :

Parallel lines :

Two straight lines which are in the same plane and do not meet , however far , they are produced in both the directions are called Parallel lines.

Four examples of parallel lines are –

(i) Track of railway line

(ii) Opposite line of a rectangle.

(iii) Opposite edge of a cube

Question no – (11)

Solution :

Four points are –

A AB, AC,BC,BD,DC and DA

Six different line can be drawn.

The lines which are concurrent at A are –

AB, AC, AD are concernment at A

Question no – (12)

Solution :

(i) Four pairs of intersecting lines.

= l , p , r ; m, r ; and m , a .

(ii) Lines which are parallel to m.

= l, n are parallel to m .

(iii) Lines whose point of concurrence is A .

concurrence in A are –

= l , r , and p

(iv) Lines whose point of intersection is H.

= lines m and q.
