Sylvia is looking for lines of symmetry in an equilateral triangle. Order the steps
that Sylvia uses to describe how she found the lines of symmetry.
a.  There are 3 ways
to fold the triangle from corner to corner.  b.  To check for
other lines of symmetry, Sylvia folds the corner to the centre of the opposite side. That didn’t
work.  c.  Sylvia concludes there are 3 lines of
symmetry.  d.  Sylvia traces the triangle and cuts it
out.

KeeKee is looking for lines of symmetry in a parallelogram. Order the steps that
KeeKee uses to describe how she found the lines of symmetry.
a.  KeeKee checks
for other lines of symmetry, she folds the parallelogram from side to side. That does not
work.  b.  She finds there are no lines of symmetry in a parallelogram.
There are no lines that divide the shape in half, so that if you fold the shape on the line the
halves match.  c.  KeeKee traces the parallelogram and cuts it
out.  d.  KeeKee folds the
parallelogram from corner to corner. That does not work.
