Identifying Similar and Congruent Figures

What does it mean for two figures to be congruent?

• They have different angle measurements and proportional side lengths.

• They have different angle measurements but the same side lengths.

• They have the same angle measurements and the same side lengths.

• They have the same angle measurements and proportional side lengths.

Which of the following is true about similar figures?

• They have the same angle measurements and proportional side lengths.

• They have different angle measurements and proportional side lengths.

• They have different angle measurements and the same side lengths.

• They have the same angle measurements and the same side lengths.

If two figures have the same angle measurements and the same side lengths, they are:

• Neither similar nor congruent

• Congruent

• Both similar and congruent

• Similar

What is the ratio of side lengths for similar figures?

• None of the above

• Equal

• 1:1

• Proportional

If two figures have the same angle measurements but different side lengths, they are:

• Neither similar nor congruent

• Similar

• Both similar and congruent

• Congruent

Which of the following is NOT a requirement for two figures to be congruent?

• Same angle measurements

• Same shape

• Same side lengths

• Proportional side lengths

Monica says two shapes are congruent because they have the same angle measurements. Makai disagrees because the side lengths are not the same. Who is correct?

• Monica

• Makai

• Both are correct

• Neither is correct

If two figures have side lengths in the ratio 21:26 and the same angle measurements, they are:

• Congruent

• Similar

• Neither similar nor congruent

• Both similar and congruent

What do the dashes in the lines of a figure indicate?

• Angle measurements

• Equal side lengths

• Proportional side lengths

• None of the above

To determine if two shapes are congruent, you need to know:

• Only the angle measurements

• Only the side lengths

• Both the angle measurements and side lengths

• Neither the angle measurements nor side lengths
