Exploring Dilations on a Coordinate Plane

The video tutorial covers the concept of dilations on a coordinate plane, explaining how scale factors affect the size of figures. It includes examples of dilating figures with different scale factors, demonstrating both enlargement and reduction. The tutorial also discusses how to find the scale factor using coordinates and compares the properties of preimage and image, such as congruence and orientation.

What happens to a figure when the scale factor is greater than one?

• The figure remains unchanged.

• The figure becomes larger.

• The figure becomes smaller.

• The figure rotates.
