How to determine the reduction scale factor for two parallelograms

The video tutorial explains how to determine if a transformation from point A to point B is an enlargement or a reduction. It focuses on calculating the scale factor, K, which must be less than one for a reduction. The tutorial provides a step-by-step example of calculating the scale factor by creating a ratio of the lengths of A and B, resulting in a scale factor of 1/3.

What is the initial step in determining whether a transformation from A to B is an enlargement or a reduction?

• Calculate the area of A and B

• Find the perimeter of A and B

• Determine if the transformation is a reduction or enlargement

• Measure the angles of A and B

What must be true about the scale factor K in a reduction?

• K must be equal to one

• K can be any positive number

• K must be greater than one

• K must be less than one

Which of the following is NOT a possible value for the scale factor K in a reduction?

• 1/2

• 2

• 1/3

• 1/4

How do you determine the scale factor when reducing from A to B?

• By multiplying the lengths of A and B

• By adding the lengths of A and B

• By creating a ratio of the lengths of B to A

• By subtracting the length of B from A

What is the scale factor when the length of A is 6 and the length of B is 2?

• 1/6

• 1/2

• 1/3

• 1/4
