WHAT IS SYMMENTRY??

DEFINE ANY TWO TYPES OF SYMENTRY.

AND GIVE TWO EXAMPLE FOR EACH

Two types of symmetry are:

1) Rotational symmetry

2) Reflection symmetry

**Rotational symmetry:**Symmetry in which parts of an object are related by rotation is called rotational symmetry.

As a general rule, you can rotate such an object through a certain angle and it will still have the same appearance.

The figure shown below shows rotational symmetry:

In (a) the figure looks the same three times during a 360-degree rotation and is said to have three-fold symmetry.

Similarly, in (b) the figure looks the same four times during a 360-degree rotation and is said to have four-fold symmetry.

**Reflection symmetry:**Reflection symmetry are those in which halves of an object are mirror images of each other.

The figure below are examples of reflection symmetry

In triangle shown, half of the image is mirror of another half. Similarly,in butterfly half part of image is mirror of anothar half.
