Are Triangle ABC and Triangle XYZ similar?

• No, corresponding angles are not congruent

• No, corresponding sides are not proportional

• Yes, corresponding angles are congruent

• Yes, corresponding sides are proportional

Which statement about the triangles at the right is true?

• ΔABC is not similar to ΔADF

• ΔABC is similar to ΔADF

• ∠BAC is not congruent to ∠DAF

• ΔABC is congruent to ΔADF

Are these triangles similar?

• Yes

• No, they are congruent

• There is not enough information to determine this

• No, they are not similar nor congruent

Ramiro says that the triangles are neither congruent nor similar because there is

not enough information given.

Is she correct?

• Ramiro is correct. The triangles are neither congruent nor similar.

• Ramiro is incorrect. The corresponding angles are congruent so the triangles are SIMILAR, and there is not enough information to determine if they are

  congruent.

• Ramiro is incorrect. The triangles are congruent

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

Julie says that the triangles are congruent because all the corresponding angles have the same measure. Is she correct?

• Julie is correct. The triangles are congruent.

• Julie is incorrect. The corresponding angles are congruent so

  the triangles are SIMILAR, and there is not enough information to determine if they are

  congruent.

• Julie is incorrect. The corresponding angles are not congruent.
