Learn Class 7 Math - Symmetry

The term symmetry refers to the shape of a particular object divided into equal parts.

In the symmetry form, one half of the mirror image is considered as the other half.

The line of symmetry is a term known as the imaginary axis through which the figure is folded.

Definition

• The shape of a given object is known as symmetry, which is divided into a different set of parts.
• Example: When we draw the heart, we usually cut the piece of paper by drawing half of the circle. And later, we cut it into a different set of parts.

A different line of symmetry

The line of symmetry is divided into three different parts. These parts are discussed here below:

• Vertical line
• Horizontal line
• Diagonal line

There are different lines of symmetry, such as one line symmetry, two-line symmetry, and three-line symmetry.

Different types of symmetry

• Translational symmetry
• Rotational symmetry
• Glide symmetry
• Reflexive symmetry

What is the meaning of point symmetry?

The term point symmetry refers to the object symmetry included with each part of the object. We can see that there are different sets of alphabets that consist of point symmetry.
