Important Questions: Symmetry - Question 1

Which of the following alphabets has a vertical line of symmetry?

Detailed Solution for Important Questions: Symmetry - Question 1

Recall definition of line symmetry. 

Important Questions: Symmetry - Question 2

Which of the following alphabets has a horizontal line of symmetry?

Detailed Solution for Important Questions: Symmetry - Question 2

All of the letters have horizontal line of symmetry since it cut them in equal parts if we draw a line in the middle of each of the letters.

Important Questions: Symmetry - Question 3

Which of the following alphabets has no line of symmetry?

Detailed Solution for Important Questions: Symmetry - Question 3

Line of symmetry: It is an imaginary line that when passes through any shape or letter, divides it into two equal halves or duplicates or we can say that when a shape or a letter is folded along the line of symmetry, the figure overlaps each other.

The letters F, G, J, L, N, P, Q, R, S and Z have no line of symmetry as the letters cannot be divided into two or more equal halves such that they overlap each other.

Important Questions: Symmetry - Question 4

Which of the following alphabets has many lines of symmetry?

Detailed Solution for Important Questions: Symmetry - Question 4

O has many lines of symmetry.

Important Questions: Symmetry - Question 5

Which of the following triangles has no line of symmetry?

Detailed Solution for Important Questions: Symmetry - Question 5

A scalene triangle has no line of symmetry.

Important Questions: Symmetry - Question 6

What is the mirror image of  in a horizontal mirror?  

Detailed Solution for Important Questions: Symmetry - Question 6

Since horizontal mirror is mirror along with the x-axis , so B will be seen as B

Important Questions: Symmetry - Question 7

Which of the following figures are symmetrical with respect to minimum two lines? 

Detailed Solution for Important Questions: Symmetry - Question 7

 figure 1 and figure 2 both has horizontal and vertical symmetry. So it has 2 lines of symmetry.

Important Questions: Symmetry - Question 8

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

Detailed Solution for Important Questions: Symmetry - Question 8

Rotational Symmetry is how many times a shape fits into itself when rotated.So when a circle is rotated by 90 degree it fits into its original space. So its order is 4 since it fits into itself 4 times. An equilateral triangle when rotated by 120 degrees fits into itself. So its order is 3. The 3rd shape rotates the same as the circle. So its order is 4.

Important Questions: Symmetry - Question 9

Line symmetry is also known as _______ symmetry.

Detailed Solution for Important Questions: Symmetry - Question 9

Line symmetry is also known as reflection symmetry.Because a mirror line resembles the line of symmetry, where one half is the mirror image of the other half.

Important Questions: Symmetry - Question 10

What is the order of rotational symmetry for the given figure? 

Important Questions: Symmetry - Question 11

Which of the following figures has only one line of symmetry?

Detailed Solution for Important Questions: Symmetry - Question 11

The second figure has only the vertical line of symmetry. So it has only 1 line of symmetry.

Important Questions: Symmetry - Question 12

Identify the number of lines of symmetry for the figure given.

Detailed Solution for Important Questions: Symmetry - Question 12

There are only two possibilities i.e., diagonal lines of symmetry. So there are two lines of symmetry.

Important Questions: Symmetry - Question 13

In the given figure, the dotted line is the line of symmetry. Which figure is formed if the given figure is reflected in the dotted line? 

Detailed Solution for Important Questions: Symmetry - Question 13


The figure formed is a rhombus.

Important Questions: Symmetry - Question 14

What is the other name for a line of symmetry of a circle?

Detailed Solution for Important Questions: Symmetry - Question 14

A diameter divides the circle into 2 equal parts. So, it can be considered as a line of symmetry.

Important Questions: Symmetry - Question 15

A In A XYZ, XY = XZ and XM⊥YZand ZP⊥XY. About which of the following is the triangle symmetrical?

Detailed Solution for Important Questions: Symmetry - Question 15


Since XY=XZ and XM⊥YZ,

∠YXM=∠ZXM. So, the triangle is symmetrical about XM as it bisects the apex angle.

Important Questions: Symmetry - Question 16

What is the order of rotational symmetry of the English alphabet Z?

Important Questions: Symmetry - Question 17

Which of these quadrilaterals have both line and rotational symmetries of order more than 3?

Important Questions: Symmetry - Question 18

Which of these letters has only rotational symmetry?

Detailed Solution for Important Questions: Symmetry - Question 18

Rotational symmetry in capital letters describes a property in which the letter looks the same after being rotated. Capital letters that have rotational symmetry are: Z, S, H, N and O.
The letters Z, S, H and N, when rotated 180 degrees clockwise or counterclockwise, will look the same after rotation completion. This is called rotational symmetry on the order of two, because there were two 90 degree rotations. The letter O has rotational symmetry on the order of one, because after being rotated by 90 degrees, it still looks the same.

Important Questions: Symmetry - Question 19

A square has a rotational symmetry of order 4 about its centre. What is the angle of rotation?

Important Questions: Symmetry - Question 20

What is the order of rotational symmetry of the figure given?
