Line and Rotational Symmetry

Front

What is line symmetry?

Back

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

Front

What is rotational symmetry?

Back

A shape has rotational symmetry if it looks the same after a certain degree of rotation around a central point.

What is a tessellation?

Back

A tessellation is a pattern made of one or more shapes that fit together without any gaps or overlaps.

Front

Which shapes can create tessellations?

Back

Regular polygons like equilateral triangles, squares, and hexagons can create tessellations.

Front

What is the difference between line symmetry and rotational symmetry?

Back

Line symmetry involves a mirror image across a line, while rotational symmetry involves a shape looking the same after rotation.
