*reflection - a "flip" - oftentimes over either the x-axis or the y-axis
*rotation - a "turn" on a certain point - oftentimes the rotation
happens in 90 degree increments
*translation - a "slide" - oftentimes both a horizontal shift & a
vertical shift (4, 2)--means 4 units to the right and up 2 units

the coordinates of the figure by the scale factor to get the
coordinates of the new figure
