How the interior angle is calculated using above equation?
In the process of calculating the included angle, if the value is a negative one, add 360° to get the actual included angle which will be the exterior included angle. When traversing is done anticlockwise, the included angles are interior, whereas in the case of clockwise traversing, these are the exterior ones. These are always measured clockwise from the preceding line to the forward line.
How to Calculate Included Angle from Two Lines?
Included Angle from Two Lines calculator uses Included Angle = Fore Bearing of Previous Line-Back Bearing of Previous Line to calculate the Included Angle, The Included Angle from Two Lines formula is defined as the interior angle made by two lines in the compass surveying. Included Angle is denoted by θ symbol.
