QUESTION: 1

How many lines of symmetries are there in regular pentagon?

Solution:

There are 5 lines in the pentagon and the symmetry line passes from vertex to the middle of the line opposite to the vertex . So, lines of symmetry are 5.

QUESTION: 2

How many lines of symmetries are there in rectangle?

Solution:

QUESTION: 3

Find the number of lines of symmetry of the following figure:

Solution:

QUESTION: 4

Find the number of lines of symmetry of the following figure:

Solution:

Yes there are only two lines of symmetry i.e. a horizontal and a vertical line of symmetry, diagonally its not symmetrical.

QUESTION: 5

Find the number of lines of symmetry in regular hexagon.

Solution:

QUESTION: 6

Letter ‘A’ of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about.

Solution:

Vertical mirror – A, H, I, M, O, T, U, V, W, X and Y

QUESTION: 7

Letter ‘B’ of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about.

Solution:

Yes , B has a horizontal line of symmetry from the middle , but does not have a vertical line of symmetry, because its not symmetrical with vertical line.

QUESTION: 8

Letter ‘C’ of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about.

Solution:

when you’ll place a horizontal mirror you’ll see that C appears C in the mirror.

QUESTION: 9

Letter ‘D’ of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about.

Solution:

When you’ll place a horizontal mirror you’ll see that D appears D in the mirror. If you place a vertical mirror D will be laterally inverted.

QUESTION: 10

Letter ‘E’ of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about.

Solution:

Horizontal mirror – B, C, D, E, H, I, O and X

QUESTION: 11

Letter ‘G’ of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about.

Solution:

Yes , G does not have any line of symmetry , if you draw it horizontally or vertically , its not symmetrical.

QUESTION: 12

Letter ‘H’ of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about.

Solution:

Letters of the English alphabet symmetric about both horizontal and vertical mirrors: -

H, I, O and X

The letters when flipped along both the axes (horizontal and vertical) retains the original figure.

QUESTION: 13

Letter ‘I’ of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about.

Solution:

‘I’ have both vertical and horizontal symmetry since horizontal division divides ’I’ symmetrical similarly it has a vertical symmetry.

QUESTION: 14

Letter ‘M’ of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about.

Solution:

QUESTION: 15

Letter ‘T’ of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about.

Solution:

T has only vertical symmetry since if we draw a horizontal line, we have ^{-}on one half but not in other half

QUESTION: 16

Solution:

QUESTION: 17

Find the number of lines of symmetry in the below figure:

Solution:

QUESTION: 18

Find the number of lines of symmetry in the below figure:

Solution:

If you draw a vertical or horizontal or diagonal line you will find that its not symmetrical. Hence, it doesn’t have any lines of symmetry.

QUESTION: 19

Find the number of lines of symmetry in the below figure:

Solution:

It has only 1 line of symmetry which is a vertical line of symmetry, as if you draw a horizontal line one half will have a face and one half will have legs which are not symmetrical.

QUESTION: 20

Find the number of lines of symmetry in the below figure:

Solution:

These are the 4 lines of symmetry
