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.

How many lines of symmetry does an equilateral triangle have?

Back

An equilateral triangle has 3 lines of symmetry.

Front

What is the difference between reflective symmetry and rotational symmetry?

Back

Reflective symmetry involves a mirror line dividing a shape into two identical halves, while rotational symmetry involves rotating a shape around a point and having it look the same at certain angles.

Front

Can a shape be symmetrical if it has no lines of symmetry?

Back

No, a shape cannot be considered symmetrical if it has no lines of symmetry.

Front

What is an example of a shape with no lines of symmetry?

Back
