Exploring Geometric Transformations: Translation

The video tutorial explains geometric translation, a type of transformation that involves moving every point of a shape the same distance in the X and Y directions. It introduces the concepts of preimage and image, and provides multiple examples of how to perform translations using coordinate changes. The tutorial also demonstrates how to write translation rules and apply them to graphing exercises.

What is another term often used for 'translation' in geometric transformations?

• Dilation

• Move

• Reflection

• Rotation
