Key facts behind this grade 4 symmetry test

Key facts

A line of symmetry splits a figure into two matching halves.
A square has 4 lines of symmetry, a rectangle has 2, and an equilateral triangle has 3.
A regular polygon with n sides has n lines of symmetry.
Some figures, like a slanted parallelogram, have no lines of symmetry.
Check by folding: the edges and corners must line up exactly.
