Triangle Similarity Quiz

Which of the following is NOT a criterion for triangle similarity?

• Angle-Side-Angle

• Side-Angle-Side

• Side-Side-Side

• Angle-Angle

If two triangles have two pairs of congruent angles, what can be concluded about the triangles?

• They are not related.

• They are identical.

• They are similar.

• They are congruent.

What must be true for triangles to be similar by the side-side-side criterion?

• All sides are equal.

• All sides are proportional.

• All angles are proportional.

• All angles are equal.

In side-angle-side similarity, where must the angle be located?

• At the base of the triangle.

• Between the two sides being compared.

• It doesn't matter where the angle is.

• At the top of the triangle.

Which of the following is a correct example of side-angle-side similarity?

• Two triangles with sides 3, 4, 5 and 6, 8, 10.

• Two triangles with sides 5, 5, 5 and 10, 10, 10.

• Two triangles with sides 6, 8, 10 and 12, 16, 20, with a congruent angle between the sides.

• Two triangles with sides 2, 3, 4 and 4, 6, 8.

In the example with triangles ABC and DBE, which angles are congruent?

• Angle A and Angle B

• Angle C and Angle E

• Angle B and Angle E

• Angle-Angle

• None of the above

In the second example, why are the triangles not similar?

• The angles are not congruent.

• The triangles are not the same size.

• The angles are not in the correct position.

• The sides are not proportional.

In the final example, what is the similarity criterion used?

• Angle-Angle

• Side-Angle-Side

• Side-Side-Side

What is the correct correspondence of vertices in the similar triangles ABC and EBD?

• A corresponds to D, B to B, C to E

• A corresponds to B, B to E, C to D

• A corresponds to C, B to D, C to E

• A corresponds to E, B to D, C to B
