Pupils multiply the vertical and horizontal distances from the center of dilation by the scale factor. The independent practice prompts the class to analyze the relationship between the image and pre-image. The lesson is...

How does something go from here to there? Describe it with a transformation. Young mathematicians learn how to translate, reflect, rotate, and dilate an image. 

Review for the test with a comprehensive list of terms and concepts for the unit on congruence and similarity. It divides divides the sections in the order of the lessons presented during the unit. 

Transformations are more than the process in which sports cars become fighting robots. Listed in terms of which transformations give congruent or similar figures, several resources provide definitions and examples of the four...

Learners consider a set of questions to determine a series of transformations that will move one figure to another. Once the series is determined, the pupil then determines whether the pre-image and image are either congruent...

An instructive lesson provides the basics on how to perform rotations on the coordinate plane. The handout also covers rotating about a point other than the origin and how to perform a series of transformations. 

This MathWorld site gives a visual description of dilation and the different kinds of dilation in a similarity transformation.

Brush up on your math skills relating to dilations then try some practice problems to test your understanding.

This site defines dilation and gives an example with a diagram. There is also an interactive activity involving a JavaSketchPad page in which you can explore dilations. In addition, be sure to follow the links to related terms, more...

This site offers a very basic discussion of dilations. It explains what a scaling factor is and provides illustrations.

Using an example of light bouncing back and forth between two mirrors in a rocket, time dilation is explained in this resource. Step-by-step calculations using Einstein's time dilation equation are shown.

Here's a solved problem in time dilation. It's still not easy to follow, but it's doable. The math is not difficult, but the mathematical thinking is demanding.

Determine the meaning of dilation through the glossary entry.

A good mathematical account of what happens to time as you approach c: the speed of light. Also provides a rather a fascinating video (fly through the Lattice) - don't miss it. Take some time and explore this site.

[Free Registration/Login may be required to access all resource tools.] Transformations move and modify geometric shapes. There are several types of transformations that all transform figures in different ways. These transformations can...

Review your understanding of relativity with this study guide.

Short and sweet definition and explanation of hyperons in the particle zoo. Nice info about time dilation making hyperon beams useful.

Find a clear explanation of similar figures. Discusses how they can be transformed through a sequence of rotations, reflections, translations, and dilations. Explanations are supported with illustrated examples.

Article with questions and answers relating to heart transplants. Great info from who is eligible, what is an average cost, what drugs are related and much more.

A decent explanation of the concept of time as the fourth dimension. The author discusses Einstein's theory of special relativity and the idea of space-time.
