Introduction to Matrix Transformations 1
Drag point P in the sketch below. As square PQRS moves, observe how P'Q'R'S' moves.
Change the elements in the spreadsheet to change the transformation matrix.
As you drag, is it possible to get P and P' to coincide? What about Q and Q'? What about the other corresponding points?
(You can click and drag on the background to move the grid.)
