Determining the scale factor of two quadrilaterals

The video tutorial explains the concepts of enlargement and reduction in geometry, focusing on how to find and simplify the scale factor between two shapes. The teacher demonstrates the process by calculating the lengths of two shapes, A and B, and determining the scale factor as 1/2. The tutorial concludes with a verification of the scale factor and a discussion on its implications.

What does it mean for two shapes to be a reduction or enlargement?

Explain the process of reducing the scale factor from A to B.
