Symmetry

Front

What is symmetry?

Back

Symmetry is when one shape becomes exactly like another if you flip, slide, or turn it.

Front

What is a line of symmetry?

Back

A line of symmetry is an imaginary line that divides a shape into two identical halves.

Front

Give an example of a symmetrical shape.

Back

A square is a symmetrical shape because it can be divided into two equal parts by its lines of symmetry.

Front

What does it mean if a shape is not symmetrical?

Back

If a shape is not symmetrical, it means that it cannot be divided into two identical halves.

Front

How many lines of symmetry does a circle have?

Back

A circle has an infinite number of lines of symmetry.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a center point and still look the same.

Front

Give an example of a shape with rotational symmetry.

Back

A star has rotational symmetry because it looks the same when rotated at certain angles.

Front

What is the order of rotational symmetry?

Back

The order of rotational symmetry is the number of times a shape fits onto itself during a full rotation (360 degrees).

Front

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

Back

You can find a line of symmetry by folding the shape in half and checking if both sides match.

Front

What is bilateral symmetry?

Back

Bilateral symmetry is when a shape can be divided into two mirror-image halves.
