D. Answer the following.

1. Draw the given shapes and show how many lines of symmetry are there in each of the following figures:

(a) a scalene triangle (b) a square (c) a parallelogram (d) a regular hexagon

2. Draw the other half of each geometric figure:

(a) (b) (c) (d)

3. Write the order of rotational symmetry for each of the following:

(a) (b) (c) (d)

4. In each of the following figures, write the number of lines of symmetry and order of rotational
symmetry.

(a) (b) 2 (c) (d) (e)

2
5. Draw a 4-sided polygon with: (a) only one line of symmetry (b) two lines of symmetry and (c) more
than three lines of symmetry.

6. Find the angle through which the letters and have been rotated clockwise to retain its original
position.

7. In word ‘MATHEMATICS’, find the letters that have vertical and horizontal lines of symmetry.

8. In the adjoining figure, take any one diagonal as a line of symmetry and shade a few more squares to

make the figure symmetric about a diagonal. Is there more than one way to do this? Will the figure
be symmetric about both the diagonals?
