Scale Factor & Using Scale Factor

What does a scale factor of 1 mean?

• It means the two shapes are the same size.

• It means one shape is larger than the other.

• It means the shapes are not comparable.

• It means the shapes are mirrored.

How do you express a scale factor of 5:2 as a decimal?

• 2.0

• 2.5

• 3.0

• 1.5

How do you find the scale factor between two shapes?

• To find the scale factor, divide the length of a side of the larger shape by the length of the corresponding side of the smaller shape.

• To find the scale factor, multiply the length of a side of the larger shape by the length of the corresponding side of the smaller shape.

• To find the scale factor, add the lengths of the corresponding sides of both shapes.

• To find the scale factor, subtract the length of the smaller shape from the length of the larger shape.

What is a scale factor?

• A number that scales or multiplies some quantity.

• A measurement of length in a specific unit.

• A ratio that compares two different shapes.

• A constant value used in equations.

If the scale factor is 1/2, how does the size of the smaller shape compare to the larger shape?

• The smaller shape is half the size of the larger shape.

• The smaller shape is twice the size of the larger shape.

• The smaller shape is the same size as the larger shape.

• The smaller shape is one-fourth the size of the larger shape.

What is the scale factor from shape A (length 4) to shape B (length 8)?

• 1

• 1.5

• 2

• 3

If a shape is enlarged by a scale factor of 3, what happens to its dimensions?

• All dimensions are multiplied by 3, making the shape larger.

• Only the height is multiplied by 3, while the width remains the same.

• The shape remains the same size, as scale factors do not affect dimensions.

• All dimensions are divided by 3, making the shape smaller.

What is the scale factor from a small rectangle (length 2) to a large rectangle (length 6)?

• 2

• 3

• 4

• 5

If the scale factor is 2, what does that mean?

• It means that the dimensions of the second shape are twice as large as the dimensions of the first shape.

• It means that the dimensions of the second shape are half as large as the dimensions of the first shape.

• It means that the dimensions of the second shape are the same as the dimensions of the first shape.

• It means that the dimensions of the second shape are three times larger than the dimensions of the first shape.

If a shape's side length is 5 and the scale factor is 4:5, what is the corresponding side length in the larger shape?

• 4

• 6

• 5

• 8
