Similarity Unit Review

Based on the drawing, which of the following statements is true?

• The triangles are similar because the lengths of the sides are congruent.

• The triangles are not similar because the corresponding angles are not congruent.

• The triangles are similar because the corresponding angles are congruent.

• Can not determine if the triangles are similar because the scale factor is unknown.
