Test: Symmetry - Grade 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.

To determine the number of lines of symmetry in the figure:

• Identify the characteristics of the shape.
• Check for vertical, horizontal, or diagonal symmetry lines.
• For each potential line of symmetry:
• Fold the shape along that line.
• Observe if both halves match perfectly.
• Count the total lines where this condition holds true.

The assessment of the figure shows that it does not have any lines of symmetry, leading to the conclusion of zero lines of symmetry.

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

The letter 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

To determine the number of lines of symmetry in the figure:

• First, identify the overall shape of the figure.
• Lines of symmetry can be found by drawing imaginary lines that divide the figure into two identical halves.
• Check for vertical, horizontal, and diagonal lines of symmetry.
• Count each unique line that achieves this division.

In conclusion, after assessing the figure, you will find the total number of lines of symmetry. Ensure to consider all possible orientations for accurate counting.

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
