Dilations from a Non-Origin Center
In this video, we will dilate figures on the coordinate plane when the center of dilation is not the origin. The first example is a standard dilation (enlargement) with a non-origin center, and the second example gives you both the...

Dilations from the Origin
In this video, we learn how to dilate figures from the origin. We do one example that is an ENLARGEMENT (has a scale factor greater than 1), and another example that is a REDUCTION (scale factor that is between 0 and 1).
