The town of Centreville wanted to put a monument at a point that is equidistant from the post office, city hall, and the police station. There are straight roads that connect the post office to city hall, the post office to the police station, and city hall to the police stations. Use what you know about perpendicular bisectors to determine where the monument should be placed. Explain how you know that the monument will be the same distance from the three buildings.
