Introduction – The line that divides an image or shape into two equal halves to form a
mirror image is called the line of symmetry.
The shape which has the line of symmetry is known as “symmetrical shape”
The shape which doesn't have the line of symmetry is known as “asymmetrical shape”
Example:
Types of Line of Symmetry
Line of symmetry can be of three types:
1.Horizontal line of symmetry(sleeping)
2.Vertical line of symmetry(standing)
3.Diagonal line of symmetry(slanting)
