The rules: Grab the nearest book to you, using no discrimination or judgement, just the nearest book. Open to page 56, and quote the 5th sentence from that page.

"First it ascertains the lower left corner (since (x0, y0) might be any one of the rectangle's four corners) and then calculates the width and height."

This comes from the popular gang of four: Design Patterns, Elements of Reusable Object-Oriented Software.
