Question 1
1 / -0

Two rays A and B having common initial point is said to form an ________.

A
Line

B
Ray

C
Line segment

D
Angle

Solution

When two rays have a common initial point, they form an angle at that point.
Hence, D will be correct answer.
Question 2
1 / -0

What is a line?

A
A collection of points in a plane

B
A collection of points going in opposite direction having no end points following a straight path

C
A path joining two points

D
A collection of points going in opposite direction.

Solution

A line is a collection of points along a straight path that goes on and on in opposite directions. It has no end points.
Question 3
1 / -0

Which of the following represent parallel lines AB and CD?

A
$$\displaystyle AB\neq CD$$

B
$$\displaystyle AB\cong CD$$

C
$$\displaystyle AB\parallel CD$$

D
$$\displaystyle AB\sim CD$$

Solution

We know that, the symbol for parallel lines is $$\parallel$$.
Hence, two lines, $$AB$$ and $$CD$$, when parallel, are represented as $$AB\parallel CD$$.

Hence, option C is correct.
Question 4
1 / -0

The length of a line is:

A
Distance between the end points

B
Distance between any two points on the line

C
Not defined

D
None of these

Solution

A line is a straight path, having no bends and extends infinitely on both the sides or we can say that a line is a path having no end points. Thus a line has no fixed length or not definite length.
Hence, C will be correct answer.
Question 5
1 / -0

Which of the following is a real life example of intersecting line?

A
Orange

B
Football

C
Hands of the clock

D
None of these

Solution

You can clearly see two lines passing through a common point in the clock shown in the figure.
No lines are observed in an orange and a football.
So option $$C$$ is correct.
Question 6
1 / -0

From the figure, identify the center of the circle.

A
$$A$$

B
$$D$$

C
$$B$$

D
$$C$$

Solution

Center of a circle is a point inside the circle and is at an equal distance from all of the points on its circumference.
In the given figure, $$C$$ is such point.
So, $$C$$ is the center of the given circle.
Hence, option $$D$$ is correct.
Question 7
1 / -0

Identify the center of the circle.

A
$$A$$

B
$$O$$

C
$$D$$

D
$$C$$

Solution

Center of a circle is a point inside the circle and is at an equal distance from all of the points on its circumference.
In the given figure, $$O$$ is such point.
So, $$O$$ is the center of the given circle.
Hence, option $$B$$ is correct.
Question 8
1 / -0

A minimum of how many lines are required for intersection?

A
$$3$$

B
$$4$$

C
$$2$$

D
None of these

Solution

A minimum of two lines are required to get a point of intersection.
So option $$C$$ is correct.
Question 9
1 / -0

Two concentric circles intersect at _____ number of points.

A
$$2$$

B
$$0$$

C
$$1$$

D
None of these

Solution

Two concentric circles do not intersect. They only share a common centre as shown in the figure.
Question 10
1 / -0

Which of the following letters represents the vertex of an angle in the given picture?

A
D and E

B
E and H

C
F and G

D
G only

E
H only

Solution

We know that the common end point of an angle is called vertex. So from the given figure, $$H$$ be a common end point. Therefore, $$H$$ is a vertex.
Hence, E is correct answer..
