 # Symmetry Class 6 Maths Notes - Chapter 13

Symmetry And Line Of Symmetry Definition –

The symmetry of an object is defined as one half of the object is a mirror image of the other half. When an object is split into half, both the sides are exactly the same. The line which divides them is called the line of symmetry. One simple example is reflection symmetry. The object can be divided into one or more than one lines of symmetry.

Below are some types of line of symmetry along with examples-

 Sl.no Type Example 1 No line of symmetry Scalene triangle 2 1 line of symmetry Isosceles triangle 3 2 lines of symmetry Rectangle 4 3 lines of symmetry Equilateral triangle
