Does your child know how to tell if two shapes are congruent? Help her learn how with this fun worksheet. If the shapes are the same in size and shape, then they are congruent. If they are the same in shape, but different in size, they are similar, but not congruent. Your child will be asked to look at a variety of shapes and color the congruent shapes the same color. It can be a challenge because the shapes aren't all facing the same way!
