Line Symmetry

In room five for maths, we had to fold a square piece of paper in half, and then we had to draw straight lines, with a ruler from the fold, then we had to cut the shapes out.  Then we had two halves of the shape and in the middle was the line of symmetry. We sorted the shapes by four sides, three sides, and more than four sides.The line of symmetry divides a shape in two.  Here is my groups work.
