7. Identify all possible lines of symmetry in the following figures:

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

(e) (f) (g) (h)

(NCERT)

8. Copy the figure given alongside. Take any one diagonal as a line of
symmetry and shade a few more squares to make the figure symmetric

about it. Is there more than one way to do that? Will the figure be
symmetric about both the diagonals?
9. Mention the number of lines of symmetry each of the following figures have:

(a) A scalene triangle (b) A parallelogram (c) A rhombus (d) A hexagon
(e) A regular octagon (f) A quadrilateral (g) h (small letter) (h) Digit eight
(i) Letter I (j) Letter K

10. Copy the diagram and complete each figure, so that it is symmetric about the given mirror
line(s):

(a) (b)

(c) (d)
