Similar Triangles Have Congruent Angles

Tell whether the triangles are similar. Explain.

• Yes because why not

• No because x = 107

• Yes because the triangles have at least two congruent angles.

• Nah

Which triangles are similar to triangle A?

• B

• C

• Both

• None

Tell whether the triangles are similar. Explain.

• Yes because it looks like it

• Yes because 36 + 72 + 33 = 180

• No because 36 + 72 + 33 =/= 180

• Def not

Find the value of x if the two triangles are similar.

• x = 45

• x = 3

• x = 12

• x = 90

Which statement about the triangles at the right is true?

• ABC is similar to ADF

• ∠BAC is not congruent to ∠DAF

• ABC is congruent to ADF

• ABC is not similar to ADF

Are the triangles similar? Explain.

• No, because only one angle of the triangles is congruent.

• Yes, because two of the angles are congruent.

• No, because only one triangle has a right angle.

• Not enough information to determine.
