"Weber's Triangle" is a paradigmatic optimum location problem, carefully exposed in textbooks about Regional Science. Finding its solution has involved so far resorting to computers or possibly using techniques resting on an analogy with mechanics. This paper proposes a geometric approach resulting in a simple and practical method for drawing the solution. Simultaneously, this method sheds its light on the limit cases of the study.
