Line Symmetry Year 4

A shape has line symmetry if… You can draw a line through it so that one part is exactly the same as the other part.

These shapes have one line of symmetry

These shapes have two lines of symmetry

Some shapes have more than 2 lines of symmetry How many lines of symmetry has a square got?

Watch! A square has 4 lines of symmetry

How many lines of symmetry does this shape have? 1 2 More than 2

Watch! This shape has 1 line of symmetry

Well done!

But how many lines of symmetry does this shape have? 1 2 More than 2

Watch! This shape has 2 lines of symmetry

Well done!

How many lines of symmetry does this shape have? 1 2 More than 2

Watch! This shape has 3 lines of symmetry

Well done!

But how many lines of symmetry does this shape have? 1 2 More than 2

Watch! This shape has only 2 lines of symmetry

Well done!

…you join two shapes together? What happens when… …you join two shapes together? Investigate.
