❓ what is backward bearing ❓

The bearing of a lime measured in the backward direction (i.,e., opposite to the direction of progress of survey) is known as Back bearing....

1→Back bearing is the bearing (angle) of the line in the opposite direction of surveying..

2→ Formula used to calculate the back bearing of line B.B= F.B 180° {+sign when F.B is less than 180° and - sign when F.B is more than 180°)..

Taking a forward bearing

Taking a forward bearing.

The first compass bearing we need to take at the lake is from our unknown location to our cabin on the far shore. The bearing we end up with represents the angle between a line from Magnetic North to our location, and a line from our location to the cabin. This bearing is a "forward bearing."

But when we go to plot this bearing on our map, we can't plot the angle from our current location since that is what we are trying to find. Instead we plot a bearing from the cabin, as if someone there took a bearing "looking BACK towards our location." This would be called a "back bearing" and will be 180° different from our "forward bearing."

How to determine a back bearing

One technique is to do the math. Add or subtract 180° from you forward bearing to get your back bearing. You want the result to fall between 0° and 360°, so if the forward bearing is less than 180°, add 180° to it, and if it's greater than 180°, subtract 180°.
