The present invention is directed toward a system for forming miter joints including a miter saw and an angle gauge. The miter saw includes a platform with a kerf slot and a pair of arcuate slots. Each arcuate slot includes an associated rail located on the underside of the platform. A fence is coupled to each of the rails such that the fence may be pivoted with respect to the platform. The angle measurement tool is a one-handed tool including spring loaded paddles that measure the angle between intersecting surfaces. The angle measurement tool connects to the miter saw to permit the transfer of the measured angle to the fences.
