Symmetry
Mathematics Solutions from Chapter -1 - Symmetry
In this chapter, different kinds of symmetries are explained with diagrams. It explains that symmetry of a figure is the phenomenon in which the figure has exactly the same shape and size. Reflections and lines of symmetry are also explained here.

This topic discusses polygons which are called regular polygons, their properties and the number of lines of symmetry each polygon has. This is followed by an activity about folding paper and relating it to mirror reflections.
Symmetry in polygons is explained in this topic. Polygon is a closed figure consisting of segments of many axes. A polygon is said to be regular if all of its sides are equal in length and all of its angles are equal.
This topic discusses the different patterns and shapes that can be divided into two mirror halves by a dotted line and includes a few activities on making a line and placing a mirror there to get the exact figure.
This topic covers line symmetry and rotational symmetry. Some objects have a line of symmetry and some have rotational symmetry. These differences are explained here in detail.
