Question 1
1 / -0

Which of the following alphabet has no lines of symmetry?

A
A

B
B

C
Q

D
O

Solution

Q neither have horizontal line of symmetry not it has vertical line of symmetry.
Question 2
1 / -0

Which of the following alphabet has many lines of symmetry?

A
A

B
O

C
Q

D
B

Solution

O has infinite lines of symmetry.
Question 3
1 / -0

Which of the following alphabet has vertical line of symmetry?

A
A

B
B

C
Q

D
E

Solution

Option A is correct because Left side of line is the mirror image of right one and vise versa.
Question 4
1 / -0

Which of the following figures have rotational symmetry of order more than 1?

A

B

C

D
All the above

Solution

Rotational symmetry of order more than 1 define that the object produces exact same image when rotated more than one about its axis. Hence all the figure shown here have more than 1 order of symmetry.
Question 5
1 / -0

The number of lines of symmetry in a parallelogram are

A
one

B
zero

C
two

D
four
Solution
Question 6
1 / -0

The number of lines of symmetry of the given figure is

A
$$6$$

B
$$12$$

C
Infinite

D
Finite

Solution

The lines through the center of the circle and passing through $$(E, B), (F, C)$$,
or$$ (A, D)$$ are three lines of symmetry. The lines through the midpoints of arcs $$EF$$ and $$CB, FA$$ and $$DC$$ and $$AB$$ through the center are the other three lines of symmetry. In total $$6$$
Question 7
1 / -0

The number of line symmetries that the given figure have---

A
$$1$$

B
$$3$$

C
$$2$$

D
$$0$$

Solution

The above-mentioned figure has no lines of symmetry as it is not an equilateral triangle or symmetrical triangle. It has 0 lines of symmetry. As it is $$scalene$$ triangle
Hence option D is the correct answer.
Question 8
1 / -0

The number of lines of symmetry for a line segment are _____.

A
Is infinite

B
One

C
Two

D
None

Solution

If AB is a line segment, then a line l, which is perpendicular bisector of AB, is the line of symmetry.
Question 9
1 / -0

The order of rotational symmetry of a ceiling fan with $$3$$ blades is

A
$$2$$

B
$$3$$

C
$$4$$

D
$$6$$

Solution

The order of rotational symmetry of a ceiling fan with three blades is three $$3$$. The three lines of symmetry are showin in the figure.

A
$$H$$

B
$$C$$

C
$$S$$

D
$$A$$

Solution

The alphabet $$H$$ has order $$2$$ linear and rotational symmetry.
