MA.3.GR.1.3 - Draw line(s) of symmetry in a two-dimensional figure and identify line-symmetric two-dimensional figures.

By Alex Meads

Symmetry

A figure is line-symmetric if it can be folded on a line to form 2 matching parts that fit EXACTLY on top of each other.

The fold line is called a line of symmetry.

​This figure is line-symmetric.

It has 2 lines of symmetry.

It can be folded on both lines into equal parts.

​This figure is line-symmetric.

It has 6 lines of symmetry.

It can be folded on each line into matching parts.

​This figure is not line-symmetric.

It has no lines of symmetry.

It cannot be folded into matching parts.

Hotspot

All of the figures have a dashed line drawn across them. Choose the figures that would fit exactly on top of each other when the figure is folded over the dashed line.
