Here is a rule about similar shapes. If you were able to shrink both shapes to the exact same size and lay one over the other, the sides of each shape would match perfectly. One figure would be completely under the other.   Look at the shapes to the right. Although these shapes are not all pointed in the same direction, they are still shaped the same. These shapes are still similar, because if we made them just the same size and turned them in the same direction, one would completely cover the other. This is the basic rule about similarity.
