Sam noticed that some new houses were being built in his neighborhood. He thought they all had the same shape but they were different sizes.

 Sam had discovered similar figures. Similar figures are figures that have the same shape. They are not the same size . They also do not have to be in the same position. |

 Look at these shapes. Click on yes if the shapes are similar. Click on no if the shapes are not similar. |

 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. |

 Look at the shapes on the following screen. Click on all shapes that are similar in each row. Remember that similar figures are the same shape but are a different size. They also do not have to be in the same position.  |
