Rotational Symmetry Practice

Front

What is rotational symmetry?

Back

Rotational symmetry is a property of a shape that looks the same after a certain amount of rotation. The shape can be rotated around a central point and still appear unchanged.

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 degrees.

Front

How do you calculate the angle of rotational symmetry?

Back

The angle of rotational symmetry can be calculated by dividing 360 degrees by the order of rotational symmetry.

Front

What is the order of rotational symmetry for a square?

Back

The order of rotational symmetry for a square is 4.

Front

What is the order of rotational symmetry for an equilateral triangle?

Back

The order of rotational symmetry for an equilateral triangle is 3.

Front

What is the angle of rotational symmetry for a shape with order 4?

Back

The angle of rotational symmetry for a shape with order 4 is 90 degrees.

Front

What is the angle of rotational symmetry for a shape with order 6?

Back

The angle of rotational symmetry for a shape with order 6 is 60 degrees.

Front

What is the order of rotational symmetry for a regular pentagon?

Back

The order of rotational symmetry for a regular pentagon is 5.

Front

How does the recycling symbol demonstrate rotational symmetry?

Back

The recycling symbol has an order of 3, meaning it can be rotated 120 degrees and still look the same.

Front

Can a shape have rotational symmetry without having reflective symmetry?

Back

Yes, a shape can have rotational symmetry without having reflective symmetry. For example, a spiral has rotational symmetry but does not have reflective symmetry.
