The angle between the prolongation of the preceding line and the forward line of a traverse is called A. deflection angle B. included angle C. direct angle D. none of the above

The correct answer is A. deflection angle.

A deflection angle is the angle between the prolongation of the preceding line and the forward line of a traverse. It is measured clockwise from north.

A included angle is the angle between two lines that share a common vertex.

A direct angle is an angle that is equal to 90 degrees.

None of the above is the correct answer because it does not describe the angle between the prolongation of the preceding line and the forward line of a traverse.
