The dotted line divides the shape into two halves. But if you
fold it along the dotted line, the left half does not cover the
right half completely. So the two halves are not mirror halves.
Now look at another shape.
If you fold it along the dotted line, one half will cover the other
similar half completely. So the two here are mirror halves.
Now imagine the same for these pictures.
On the next page, children need to understand that even though the shape is symmetric, the
colour scheme of the figure can make it asymmetric (e.g. in shapes 10 and 12). Encourage
children to look for asymmetry based on the shape as well as the colour scheme.
