The way to see lines of symmetry is to imagine folding the shape into two matching halves - just like when you make a paper airplane.

# Using Symmetry - Properties of 2D Shapes

This Math quiz is called 'Using Symmetry - Properties of 2D Shapes' and it has been written by teachers to help you if you are studying the subject at elementary school. Playing educational quizzes is an enjoyable way to learn if you are in the 3rd, 4th or 5th grade - aged 8 to 11.

This quiz deals with identifying and describing the properties of 2-D shapes, including the number of sides and line symmetry in a vertical line.

In elementary school children are taught to identify some of the properties of 2-dimensional shapes. They will begin to explore this for themselves, perhaps by folding a shape exactly in half - the fold line then shows one line of symmetry.

This quiz will help children to identify the property of symmetry in a variety of 2-dimensional shapes.

Can you recognize the lines of symmetry in these shapes?
