Location Transport

How do I find a location that is central to four others?

I want to know how to find a location that is central to four others. This isn't some homework problem, or anything, it's just me wanting to know something. I want to know what the central location is to four cities, using straight lines, as opposed to using driving routes between those locations. So how would I do this without printing a map out and just drawing the lines out?

1. If you don't want to print it out, just press the Prt Sc button (print screen) and draw the lines in paint or something, sorry that I can't help more than that :)
2. Internet... or use Google Earth.
