Triangle Similarity Quiz

What are the three methods used to prove triangle similarity?

• Angle-Angle, Side-Side-Side, Angle-Side-Angle

• Angle-Angle, Side-Side-Side, Side-Angle-Side

• Angle-Angle, Angle-Side-Angle, Side-Angle-Side

• Angle-Side-Angle, Side-Side-Side, Side-Angle-Side

In the Angle-Angle method, how many pairs of congruent angles are needed to prove similarity?

• One pair

• No pairs

• Two pairs

• Three pairs

Which of the following is NOT a valid reason for angle congruence in the AA method?

• Vertical angles

• Alternate interior angles

• Corresponding angles

• Adjacent angles

What must be true about the sides in the Side-Side-Side method?

• They must be parallel

• They must form a right triangle

• They must be proportional

• They must be equal in length

How can you verify that sides are proportional in the SSS method?

• By calculating the scale factor

• By checking if they are equal

• By using a protractor

• By measuring the angles

In the SAS method, where must the angle be located?

• At the base of the triangle

• Outside the triangle

• At the apex of the triangle

• Between the two sides

What happens if the sides in the SAS method are not proportional?

• The triangles are isosceles

• The triangles are still similar

• The triangles are congruent

• The triangles are not similar

Which method would you use if you only know the angles of the triangles?

• None of the above

• Side-Side-Side

• Angle-Angle

• Side-Angle-Side

If two triangles have sides in the ratio 2:3, what can be said about their similarity?

• They are congruent

• They are not similar

• They are similar by SAS

• They are similar by SSS

What is the result if two triangles have one pair of congruent angles and proportional sides around it?

• The triangles are congruent

• The triangles are not similar

• The triangles are similar by SSS

• The triangles are similar by SAS
