5. INTRODUCTION
In order to motivate the pupils and to create a learning
atmosphere, the teacher will ask the following questions to
the pupils –
 Have you ever noticed the configuration of things like a leaf,
a papaya, a spider
 Have you seen the two equal parts of the following pictures?

6. SYMMETRY
Every leaf has two identical side.

7. All the figures can be fold into two halves.
The figures or objects which can be fold or
cut into two identical halves are called as
symmetrical objects. Which is known as
symmetry.
DEFINITION OF SYMMETRY

8. LINES OF SYMMETRY
The lines through which the figures can be fold into identical halves are
known as lines of symmetry.

9. The number of symmetrical lines of these regular polygons is equal to
their number of sides.

10. ROTATIONAL SYMMETRY
After a rotation of 120 degree the figure will posses an identical of the initial.
Order of rotation = 3
Angle of rotation = 120 degree
(a) (b) (c)

11. ROTATIONAL PATTERN OF A SQUARE
ANGLE OF ROTATION
A SQUARE HAS FOUR ROTATIONAL ORDER, AFTER A ROTATION OF 90
DEGREE A SQUARE POSSES ANOTHER IDENTICAL SQUARE
ROTAIONAL ANGLE= 90 DEGREE

12. EVALUATION AND HOMEWORK
Answer the following:
1) Can you tell the order of rotational symmetry of the equilateral triangle?
