I can use proportions to find missing lengths in similar figures.

 Same shape, but not necessarily same size  You can use proportions to find missing side lengths of similar figures.  The symbol ∼ means “is similar to”

 ∆ABC ∼ ∆FGH  This means the triangles are similar.  In similar figures, corresponding angles are equal, and corresponding side lengths are proportional. ◦ The order of the letters when making similar figures is important

 Using the same figure, find AC
