First decide if the triangles below are similar. Then, if they are similar, use the information in each diagram to solve for .

If only two pair of corresponding sides have equal ratios, can you conclude that the triangles are similar?

Careful!

The two triangles are similar (by AA~).

Draw two separate triangles, then write a proportion and solve for
