Example
If you were to cut these shapes out of flat paper, you could fold
the paper along a line of symmetry. The two halves would match.
Some shapes have more than one line of
symmetry. The shapes of most anemones
and sea stars can fold along two, three,
or more lines of symmetry.
Sketch each shape. Then draw any lines of symmetry.
If there are none, write ”zero.“
