What is rotation symmetry?

Back

A shape has rotation symmetry if it can be rotated around a central point and still look the same at certain angles.

Front

What is reflection symmetry?

Back

Symmetry where one half is the reflection of the other half.

Front

How many lines of symmetry does a circle have?

Back

An infinite number of lines of symmetry.

Front

What is a line of symmetry?

Back

An imaginary line where you can fold the image and both sides will match.

Front

Which letter has reflection symmetry?

Back

B, C, D, H, I, K, O, X, and others.

Front

Which letter has rotational symmetry?

Back

N, S, Z, H, and others.

Front

What is the difference between rotation and reflection symmetry?

Back

Rotation symmetry involves turning the shape around a point, while reflection symmetry involves flipping the shape over a line.

Front

Can a shape have both rotation and reflection symmetry?

Back

Yes, some shapes can have both types of symmetry.

Front

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

Back

A scalene triangle.

Front

How do you determine the number of lines of symmetry in a shape?

Back

By identifying all the lines where the shape can be folded to match both sides.
