In this worksheet, students will identify the lines of symmetry for the given 2D shapes.

'Practise Identifying Lines of Symmetry ' worksheet

Key stage:  KS 2

Year:  Year 4 Maths worksheets

Curriculum topic:   Geometry: Properties of Shapes

Curriculum subtopic:   Identify Line Symmetry in 2D Shapes

Difficulty level:  

Worksheet Overview

In this activity, we will be learning how to spot lines of symmetry in some rather tricky shapes!

 

Remember: A line of symmetry divides a shape into two matching parts, which will overlap each other exactly when folded along the line of symmetry.

 

Let's look at two examples.

 

Example 1

Look at this regular hexagon.

Is line a a line of symmetry?

 

a regular hexagon

 

Answer

When we reflect or fold it in the line a, we get:

 

 

This is a match!

Line a is a line of symmetry.

 

Example 2

Look at this regular hexagon.

Is line b a line of symmetry?

 

a regular hexagon

 

Answer

When we reflect it in the line b, we get:

 

 

This is not a match!

Line b is not a line of symmetry.

 

Of course, a regular hexagon has a total of six lines of symmetry, but not all of them were shown.

 

Let's have a go at some questions now.
