How to perform a dilation when the center is not the origin
In short: Mastering geometric transformations requires more than just simple scaling. This video demonstrates the algebraic steps needed to dilate a figure around any point on a plane.
The tutorial explains a three-step process for complex dilations: first, shifting the plane so the chosen center aligns with the origin; second, performing the dilation about the origin; and finally, translating the plane back to its original position.
