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.

How do you determine if you are enlarging or reducing from A to B?

What is the scale factor K when reducing from A to B?

What is the length of A as mentioned in the text?

What is the rational form of the portion when going from A to B?

What does the scale factor indicate about the size of B compared to A?
