Line and Rotational Symmetry

Front

What is line symmetry?

Back

Line symmetry, also known as reflection symmetry, occurs when a shape can be divided into two identical halves that are mirror images of each other along a line.

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 an example of a shape with rotational symmetry of order 3?

Back

An equilateral triangle has rotational symmetry of order 3.

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.

Front

Can a shape have both line and rotational symmetry?

Back

Yes, many shapes, such as squares and circles, have both line and rotational symmetry.
