Understanding Similar Polygons

What is the main difference between similar and congruent polygons?

• Congruent polygons have different shapes but the same size.

• Congruent polygons have different sizes and shapes.

• Similar polygons have the same size and shape.

• Similar polygons have the same shape but different sizes.

Which of the following is true for similar polygons?

• Corresponding sides are not proportional.

• Corresponding angles are equal.

• Corresponding sides are equal.

• Corresponding angles are not equal.

Why is the order important when setting up proportions for similar polygons?

• It determines the color of the polygon.

• It ensures the correct sides are compared.

• It helps in identifying the type of polygon.

• It affects the number of sides in the polygon.

What is the scale factor if side AB of triangle ABC is 3 and side DE of triangle DEF is 6?

• 1/3

• 1/2

• 2

• 3

How can you determine if two triangles are similar?

• By checking if all angles are congruent and sides are proportional.

• By checking if all sides are equal.

• By checking if they have the same perimeter.

• By checking if they have the same area.

In a pair of similar parallelograms, if one side of the first is 5 and the corresponding side of the second is 10, what is the scale factor?

• 1/2

• 2

• 1

• 5

What is the first step in solving for a missing side in similar polygons?

• Guessing the length of the side.

• Calculating the area of the polygon.

• Setting up a proportion using known side lengths.

• Measuring the side directly.

If two polygons are similar and one has a side length of 8 while the corresponding side in the other is 16, what is the scale factor?

• 4

• 2

• 1/4

• 1/2

Which method can be used to solve for a variable in a proportion?

• Division

• Subtraction

• Addition

• Cross-multiplication

When setting up proportions for similar polygons, what must be consistent?

• The order of corresponding sides

• The type of polygons

• The number of sides

• The color of the polygons
