Ratio Proportion and Similar Figures

Line CB corresponds with what line? 

• SR

• PQ

• SP

• RQ

Tell whether the two figures are similar. Explain your reasoning.

• Yes, similar because they have the same shape and the same angles

• No, the ratio of corresponding sides are not equal 

• Yes, same shape

• No, different sizes

All angles in similar figures are congruent.  

• True

• False

State if the triangles in each pair are similar. If so, state how you know they are similar.

• Yes, AA Similarity

• Yes, SSS Similarity

• Yes, SAS Similarity

• Not Similar

State if the triangles in each pair are similar. If so, state how you know they are similar.

• Yes, AA Similarity

• Yes, SSS Similarity

• Yes, SAS Similarity

• Not Similar

Tell whether the two figures are similar. Explain your reasoning.

• Yes, similar because corresponding angles are congruent and corresponding sides are in proportion.

• No, not similar because corresponding angles are congruent, but corresponding sides are NOT in proportion.

• Yes, same shape

• No, different sizes

Tell whether the two figures are similar. Explain your reasoning.

• Yes, similar because they are the same shape and side lengths are proportional.

• No, not similar because they are the same shape, but side lengths are not proportional.

• Yes, same shape

• No, different sizes

All angles in similar figures are congruent (equal).  

• True

• False
