Line of Symmetry
A straight line that divides a figure into two identical halves that completely match when folded over the line.
Symmetrical Figures
Shapes or objects that look exactly the same on both sides of a dividing line, like a butterfly or a square.
Asymmetrical Figures
Shapes that do not have any line of symmetry, meaning they cannot be divided into two identical halves.
Multiple Lines of Symmetry
Some special shapes, like a square or a circle, can have more than one line of symmetry passing through their center.
Mirror Halves
Two halves of a symmetrical shape that look like mirror images of each other across the line of symmetry.

In the Haryana (BSEH) Class 5 Mathematics examinations, this chapter typically carries about 4 to 6 marks. Common question types include drawing the line of symmetry for given figures, completing the other half of a symmetrical design on dotted grids, and identifying whether given shapes or English letters are symmetrical or not.
Frequently Asked Questions
What is a line of symmetry?
It is an imaginary line that cuts a shape into two exact mirror-image halves.
Do all shapes have a line of symmetry?
No, only symmetrical shapes have a line of symmetry. Asymmetrical shapes do not have any.
How many lines of symmetry does a circle have?
A circle has an infinite number of lines of symmetry because any line passing through its center divides it into two equal halves.
