(a) (b) (c)

Solution: (a) (b) (c)

Example 3: Which letters of the word ‘SYMMETRY’ are symmetrical? Also check if they have vertical
or horizontal line of symmetry.

Solution: The letters ‘S’ and ‘R’ have no lines of symmetry, ‘Y’, ‘M’, ‘T’ have vertical line of symmetry
and ‘E’ has horizontal line of symmetry as shown below:

Example 4: Draw the other half in the following figures if the dotted line is the line of symmetry.
(a) (b) (c)

Solution: (a) (b) (c)
