Similar Figures

Front

If two triangles are similar, what can we say about their corresponding angles?

Back

They are congruent.

Front

What is the relationship between the lengths of corresponding sides of similar figures?

Back

They are proportional.

Front

If triangle ABC is similar to triangle DEF, what can we say about the ratios of their corresponding sides?

Back

The ratios are equal.
