An angle sensor has a miter bar, a fence, a rotary sensor, a display, and a processing system and may additionally have a head plate, an auxiliary fence, means for detachably affixing the miter bar to a saw blade, and a power source. The miter bar has a longitudinal axis. Primary fence 6 is pivotally disposed on the miter bar and has a face that defines a plane. The rotary sensor outputs a signal indicative of the angle between the longitudinal axis of the miter bar and the plane of the face. The processing system interprets the signal and activates the display to numerically exhibit the angle. The display provides a visual indication of the angle.
