How to Triangulate a Cell Phone

1. Turn on the cell phone. A live cell phone is in continual relay with surrounding cell phone towers to ensure the strongest signal, meaning the phone must be on to send a signal.
2. Note the location of the signal tower receiving the strongest signal. Draw its coverage radius. You now have one point with a circle and know that the phone is located somewhere within that ring.
3. Add a second tower's radius and location receiving a signal from your cell phone. The overlapping between these two spheres narrows the choices your phone is located to two points.
4. Place the signal strength of a third tower receiving a signal from your cell phone with the other two. At the point where these three orbits intersect you have the location of the cell phone.
