Some figures or objects have more than one line of symmetry. These lines of symmetry
can be vertical, horizontal or diagonal.
Be Aware
You can draw
infinite diameters
in a circle, so it
has infinite lines
Three lines of symmetry Two lines of symmetry Four lines of symmetry of symmetry.
activity Creative Thinking
Take a sheet of paper and fold it in half twice.
Cut out any shapes on the corners with a pair of scissors and unfold the paper.
⇒ ⇒ ⇒ ⇒
The figure so obtained will look identical if folded along any of the dotted lines.
The design so formed by cutting is symmetrical because when folded on any of
the dotted lines, both the halves overlap each other.
The square design shown above has 2 lines of symmetry.
Some letters of the English alphabet also show symmetry.
Think Tank Creative Thinking
1. Is there any number from 0 to 9 which has a line
of symmetry? If yes, write them.
2. Identify at least three letters in the English alphabet that
have more than one line of symmetry.
Practice time 8A
1. Which of the following figures are symmetrical?
(a) (b) (c) (d)
(e) (f) (g) (h)
teacher’s Discuss with students with examples that, there are some shapes or letters of the English alphabet that are
tip not symmetrical, these shapes are called asymmetrical.
