P. 134
Example 1: List any four symmetrical objects.
Solution: A pair of scissors, spectacles, blackboard/whiteboard and an apple.
Example 2: For the given figure, which one is the mirror line, AB or CD? C
Solution: The given figure is symmetrical about the line CD since it is the
A B
mirror line that divides the figure into two similar halves.
Example 3: Check whether the given figures are symmetrical or not. If the
figures are symmetrical, draw the line(s) of symmetry.
D
(a) (b) (c)
(d) (e) (f)
Solution: Figures (a), (b), (d) and (f) are symmetrical while figures (c) and (e) are not
symmetrical.
(a) (b) (d) (f)
Example 4: Complete the following figures to create 2D symmetrical shapes.
(a) (b)
(c) (d)
