Included Angle Definition (Illustrated Mathematics Dictionary)

WebWhen surveyors measure angles, the resultant calculations are typically reported as either azimuths or bearings, as seen in Figure 5.12. A bearing is an angle less than 90° within a quadrant defined by the cardinal … WebIn land surveying, a bearing is a clockwise or counterclockwise angle between north or south and a direction. In surveying , bearings can be referenced to true north, magnetic north, grid north (the Y-axis of a map projection), or a previous map, which is often a historical magnetic north. WebThe magnetic needle is disturbed from its normal position if it is under the influence of external attractive forces called the sources of local attraction. Such a disturbing influence is known as local attraction. The term is also used to denote the amount of deviation of the needle from its normal position. The local attractive sources may be ... chinatown flushing shuttle bus

Webangle, ∆, intersects with the arc of the curve. LC is the long chord distance from the PC to the PT. The radius, R, is the distance from the arc to the center of the circle. The central angle is the same as the deflection angle measured at the PI from the back tangent (PC to PI) to the forward tangent (from PI to PT).
