Rotation and Reflection Symmetry

Front

What is rotational symmetry?

Back

A shape still looks the same after being rotated.

Front

What is the type of symmetry that involves turning an image?

Back

Rotational Symmetry.

Front

Is this rotation or reflection symmetry? (Image of a shape with reflection symmetry)

Back

Reflection.

Front

Is this shape symmetrical? (Image of a non-symmetrical shape)

Back

Not symmetrical.

Front

How many lines of symmetry does a regular hexagon have?

Back

6.

Front

Define reflection symmetry.

Back

A shape has reflection symmetry if it can be divided into two identical halves that are mirror images of each other.

Front

What is an example of a shape with rotational symmetry?

Back

A square has rotational symmetry of order 4.

Front

How do you determine the order of rotational symmetry?

Back

Count how many times a shape can be rotated to look the same within a full 360-degree rotation.

Front

What is line symmetry?

Back

Line symmetry occurs when a shape can be folded along a line so that the two halves match.

Front

Can a shape have both rotational and reflection symmetry?

Back

Yes, for example, a circle has both types of symmetry.
