Matching angles are called

• Corresponding Sides

• Corresponding Angles

• The Same

• Congruent Angles

Matching sides are called

• Corresponding Sides

• Corresponding Angles

• The Same

• Congruent Sides

Sides in similar figures must be proportional.  

• True

• False 

Choose the similarity statement for the triangles.

• ΔMNL ∼ ΔOPQ

• ΔNOM ∼ ΔPQL

• ΔLMN ∼ ΔPQO

• ΔMLN ∼ ΔPQO

What is ratio of any two corresponding sides?

• Scale Factor

• Corresponding Sides

• Similar Figures

Are the following similar? Why or why not?

• Yes. The ratios of the corresponding sides are equal.

• No. The ratios of the corresponding sides are not equal.

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

What is the similarity statement for the triangle pair?

• ΔXYZ~ΔNEW

• ΔXZY~ΔNWE

• ΔZYX~ΔENW

• ΔYZX~ΔNWE

Are the two figures similar?

• yes

• no

All corresponding angles are congruent in similar figures.

• True

• False
