Dilations

The video lesson on dilations covers identifying and performing dilations on a coordinate plane. It begins with an introduction and objectives, followed by a vocabulary review. Real-world examples illustrate dilations, and the concept of scale factor is explained. Instructions for dilating figures on a coordinate plane are provided, with practice problems to reinforce learning. The lesson concludes with a summary of key points.

What is a dilation in the context of geometry?

How can you determine if a dilation is a reduction or an enlargement?

What is the center of dilation?

What does the scale factor indicate in a dilation?

Explain the relationship between similar figures and dilations.

Provide an example of a real-world application of dilations.

What is the difference between a dilation that is a reduction and one that is an enlargement?

What happens to the coordinates of a triangle when it is dilated by a scale factor of 2?

Describe how to dilate a figure on a coordinate plane.

How do you verify that a dilation has been performed correctly?
