Understanding Scale Factors in Geometry

This video tutorial covers the concept of making scaled copies, focusing on the use of scale factors to multiply side lengths of figures. It provides step-by-step instructions for drawing scaled copies using different scale factors, such as 3 and 1/2, and discusses the operations involved in scaling. The video also includes examples of creating scaled copies with various scale factors, emphasizing the importance of consistent multiplication across all side lengths.

What is a scale factor in the context of scaled copies?

• A number used to divide each side length

• A number used to add to each side length

• A number used to multiply each side length

• A number used to subtract from each side length

If a scale factor is greater than 1, what happens to the figure?

• The figure disappears

• The figure gets smaller

• The figure remains the same size

• The figure gets larger

When using a scale factor of 3, what operation is performed on each side length?

• Each side length is multiplied by 3

• Each side length is divided by 3

• Each side length is subtracted by 3

• Each side length is added to 3

What is the result of applying a scale factor of 1/2 to a side length?

• The side length is doubled

• The side length is tripled

• The side length is halved

• The side length remains unchanged

What mistake did Diego make in his scaled copy?

• He multiplied each side length by the same factor

• He subtracted the same number from each side length

• He divided each side length by the same factor

• He added the same number to each side length

How do you determine the scale factor if a side length changes from 4 to 8 units?

• Add 4 to 8

• Divide 8 by 4

• Subtract 4 from 8

• Multiply 4 by 2

What is the primary operation used to create scaled copies?

• Addition

• Division

• Subtraction

• Multiplication

If a scale factor is less than 1, what happens to the figure?

• The figure gets larger

• The figure disappears

• The figure gets smaller

• The figure remains the same size
