Symmetry Flashcard - Year 5

Front

What is symmetry?

Back

When a shape has two sides that are exactly the same shape, colour, or size.

Front

What is a line of symmetry?

Back

A line that divides a shape into two identical parts.

Front

Can you give an example of a symmetrical shape?

Back

A square is a symmetrical shape because it can be divided into two equal halves.

Front

What happens when you fold a symmetrical shape in half?

Back

The two halves match exactly.

Front

What is rotational symmetry?

Back

When a shape can be rotated around a center point and still look the same.

Front

How many lines of symmetry does a circle have?

Back

A circle has an infinite number of lines of symmetry.

Front

What is an example of a shape with no symmetry?

Back

An irregular shape, like a starfish, has no lines of symmetry.

Front

What is the shape obtained when you fold a rectangle in half?

Back

Two equal rectangles.

Front

What is the difference between reflectional and rotational symmetry?

Back

Reflectional symmetry involves flipping a shape, while rotational symmetry involves turning a shape.

Front

How can you find a line of symmetry in a shape?

Back

By folding the shape to see if both halves match.
