Question 71.

Maximum and minimum number of points of intersection of three lines are A and B respectively. Then A+B = ?

Discuss Question

Answer: Option A. ->
:

Three lines can intersect at 3 points (Maximum)

So, A = 3

Minimum number of points of intersection of three lines will be 1

So, B = 1

Hence, A + B = (3 +1) = 4.

Question 72.

When three lines intersect each other at three different points, then how many angles will be formed?

Discuss Question

Answer: Option C. -> 12
:
C

In the figure above, three lines AB, BC and AC intersect each other at three points A, B, and C.

Total angles subtended at point A = 4. (As shown in the figure)

Similarly, four angles are subtended at points B and C.

Hence, the total number of angles that are formed when three lines intersect at three points = 4 + 4 + 4 = 12.

Question 73.

Two lines are such that they don't have any point in common to each other. Then these two lines are called as _______.

intersecting lines
parallel lines
(a) and (b) above.
None of the above

Discuss Question

Answer: Option B. -> parallel lines
:
B

If two lines don't have any points in common that means they don't have any point of intersection and hence they are parallel lines.

Question 74.

There are two points in a plane. If you join these two points, then you will get a _____.

ray
line segment
line
collection of points

Discuss Question

Answer: Option B. -> line segment
:
B

If you join any two points on a plane surface, a line segment will form since the surface is flat as given in the figure.

Question 75.

Pavan says letter D is a polygon. Is he correct?

True
False
12
24

Discuss Question

Answer: Option B. -> False
:
B

A polygon is any 2-dimensional closed figure formed with straight lines only.

In letter D, there is one line & one curve.

So, letter D is not a polygon.

Question 76.

The figure shown is a ___

Discuss Question

Answer: Option B. -> False
:

The figure shown is an open curve

Question 77.

Take two sticks and a piece of rope. Drive one stick into the ground. Form two loops, one at each end of the rope. Place one loop around the stick at the centre. Put the other around the other stick. Keep the sticks vertical to the ground. Keep the rope taut all the time and trace the path.

The figure obtained will be __.

Discuss Question

Answer: Option B. -> False
:

A circle is a set of points on a plane which are at the same distance from a fixed point called centre.

Question 78.

The given figure shows map of a village. A denotes the location of a temple and B represents location of a school. A and B in mathematical terms are called __.
