Class 7 Maths Symmetry Introduction


Symmetry is when two or more parts are identical after a flip, slide or turn. It is an important concept which is used in every field of activity.

The simplest type of Symmetry is Reflection or Mirror of an object as shown in the given figure.


This is a line symmetry. A figure or an object has a line symmetry if there is a line about which the figure may be folded so that the two parts of the figure will coincide i.e. it looks like the same as shown in the figure.
