##### About NCERT Solutions for Class 7 Maths Chapter 12

In 7 Maths Chapter 12 Symmetry, we will study about Line of symmetry for regular polygons like equilateral triangle, square, regular pentagon, hexagon, etc., calculating the number of lines of symmetry for the different figures like an equilateral triangle, an isosceles triangle, a scalene triangle, a square, a rectangle, a rhombus, a parallelogram, a regular hexagon, a circle, etc. Here, we also study about rotational symmetry like fan and other rotating objects. Consider the following terms regarding rotational symmetry:

**1. Angle of Rotation**: The angle of turning during rotation is called the angle of rotation. A full turn means a rotation of 360°, the degree measure of the angle of rotation for a half-turn is 180° and for a a quarter-turn is 90°.

**2. Centre of Rotation**: When an object rotates, its shape and size do not change. The rotation turns an object about a fixed point. This fixed point is the centre of rotation.

Some shapes have only one line of symmetry, like the letter E, some have only rotational symmetry, like the letter S and some have both symmetries like the letter H.
