Symmetry

Front

What is symmetry?

Back

Symmetry is a property where a shape or object can be divided into parts that are identical or mirror images of each other.

Front

What is a line of symmetry?

Back

A line of symmetry is an imaginary line that divides a shape into two identical halves that are mirror images of each other.

Front

How many lines of symmetry does a square have?

Back

A square has 4 lines of symmetry.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a central 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 degrees.

Front

How many orders of rotational symmetry does a circle have?

Back

A circle has infinite orders of rotational symmetry.

Front

Which letter has line symmetry: A, B, C, D?

Back

Letters A, B, and D have line symmetry; C does not.

Front

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

Back

A regular pentagon has an order of rotational symmetry of 5.

Front

If a shape has 2 lines of symmetry, what could it be?

Back

It could be a rectangle or an isosceles triangle.

Front

What is the difference between line symmetry and rotational symmetry?

Back

Line symmetry involves dividing a shape into mirror-image halves, while rotational symmetry involves rotating a shape around a point and having it look the same.
