Use the interactive transformation tool to perform dilations for four problems. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Find both the center and the scale factor of a dilation that maps a given figure to another one. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login may be required to access all resource tools.] In this lesson students explore geometric dilations. Students examine guided notes, review guided practice, watch instructional videos and attempt practice problems.

Oswego City School District provides a three link tutorial on dilations. By clicking on each of these links, you will find the definition of a dilation, examples of dilations, and a quiz to test your skills.

To make sense of this, you have to first see the Twin Paradox: Introduction, which is the special relativity version and is linked to this page. This general relativity explanation views the paradox from a gravitational point of view.
