3-90.

Determine which of the following pairs of triangles are similar. Explain your work. Homework Help ✎

1. Find the missing angle measure for each triangle to see if $\text{AA}\sim$ applies.

The triangles are not similar because they have different angle measures.

1. Find the missing angle measure for each triangle to see if $\text{AA}\sim$ applies.

• Write a ratio for each pair of sides. If the triangles are similar, all three ratios should be equal.

Is this true?

$\frac{14}{7}=\frac{12}{6}=\frac{16}{8}$
