Front

What is symmetry?

Back

Symmetry is a property where a shape or object is identical on both sides of a dividing line or around a central point.

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 an equilateral triangle have?

Back

An equilateral triangle has 3 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.

How many lines of symmetry does a regular pentagon have?

Back

A regular pentagon has 5 lines of symmetry.

Front

What is the difference between reflective and rotational symmetry?

Back

Reflective symmetry involves a line that divides a shape into mirror-image halves, while rotational symmetry involves rotating a shape around a point.
