Understanding Triangle Congruence and Similarity

What does it mean for two triangles to be congruent?

• All angles and sides are equal.

• All angles are equal, but sides are proportional.

• Only one angle and one side are equal.

• All sides are equal, but angles are proportional.

In a congruence statement, why is the order of letters important?

• It determines the size of the triangles.

• It indicates which angles and sides correspond.

• It shows the color of the triangles.

• It helps in calculating the area.

How do similar triangles differ from congruent triangles?

• Similar triangles have equal sides.

• Similar triangles have proportional sides.

• Similar triangles have different angles.

• Similar triangles have no corresponding parts.

What remains true about the angles in similar triangles?

• They are different.

• They are supplementary.

• They are congruent.

• They are proportional.

What is a statement of proportionality?

• A statement showing proportional sides.

• A statement showing equal sides.

• A statement showing different angles.

• A statement showing equal angles.

Which method is NOT used to verify proportionality?

• Cross multiplication

• Decimal conversion

• Simplifying fractions

• Measuring angles

When checking for similarity, what must be compared?

• Only the largest sides

• Only the smallest angles

• Corresponding sides and angles

• Only the perimeter

How can missing side lengths in similar triangles be found?

• By measuring directly

• By using a calculator

• By guessing

• By setting up a proportionality

What is essential to know when determining a similarity ratio?

• The area of the figures

• The order of comparison

• The color of the figures

• The volume of the figures

What does the scale factor represent in similar figures?

• The sum of all sides

• The difference in perimeters

• The ratio of new to old side lengths

• The difference in angles
