Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a center point and still look the same 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 of 360°.

Front

How do you calculate the angle of rotational symmetry?

Back

Angle of rotational symmetry = 360° / order of rotational symmetry.

Front

What is a line of symmetry?

Back

A line of symmetry is a line that divides a shape into two identical parts.

Front

Can a shape have more than one line of symmetry?

Back

Yes, shapes like squares and circles can have multiple lines of symmetry.
