Test: Symmetry - Class 7 MCQ

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.

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

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

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.

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

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.

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

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

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.

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

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

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.

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.

These are the 4 lines of symmetry
