Now, would you like me to explain plane geometry to you?

Consider the following problem: Is it possible for Whittington to have approached Cheney from behind, and never reached within 30 yards of him yet end up to Cheney's side or, in fact, in front of him?

The answer is yes. Feel free to draw a diagram if it helps.

Hint: Let Cheney be the center of a circle...
