In this lesson, we are going to go over congruent and similar solids. Whenever we have two solids that are either similar or congruent, there is a scale factor. A scale factor is just the ratio that compares the two solids; it is the ratio of the corresponding measures (it has to be corresponding). For congruent solids, these have to be true: the corresponding angles are congruent; the corresponding edges are congruent; the areas of the faces are congruent; and the volumes have to be congruent. And congruent solids have the same size and same shape. This lesson also covers similar solids.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
