The measures of the angles in a triangle are 53⁰,78⁰, and 49⁰. A similar triangle is created by using a dilation with a scale factor of 2. What are the measures of the angles of this triangle?

There is not enough information to answer this question.

Which of the statements is true about the graphed triangles?

They are similar, because the image can be obtained by dilating about the origin with a scale factor of 1/2.

They are similar, because the image can be obtained by dilating about the origin with a scale factor of 2.

They are not similar, because the image can be obtained by dilating about the origin with a scale factor of 2.

They are not similar, because the image can be obtained by dilating about the origin with a scale factor of 1/2.

In triangles TUW and WXT, ∠U and ∠X are congruent. Andre wants to prove that these triangles are similar. Which of the following is a counterexample to show that triangles TUW and WXT are NOT similar?

∠U ≅ ∠X, but ∠UTW is not congruent to ∠XWT

∠U ≅ ∠X, but ∠UWT ≅ ∠XTW and ∠UTW ≅ ∠XWT.

∠U ≅ ∠X, but ∠UWT ≅ ∠UTW and ∠XTW ≅ ∠XWT

∠UWT ≅ ∠UTW, ∠XTW ≅ ∠XWT, but ∠U is not congruent to ∠X.

If triangles MNO and PQR are similar, which of the following must be true? Select all that apply.

∠N ≅ ∠PQR, ∠M ≅ ∠QPR, ∠O ≅ ∠QRP

∠N ≅ ∠QRP, ∠M ≅ ∠QPR, ∠O ≅ ∠PQR

Which is NOT true about similar triangles.

The triangles must have at least one side that is the same length.

The angles in the triangles are congruent to each other.

The sides are proportional to each other.

The angles in each triangle add up to 180 o .
