Ans: 90.0 Since, axial trace is perpendicular to the fold axis so the fold should be a vertical fold. For any vertical fold the dip of limb will be 90 degrees.
sir, in case of symmetrical fold, the hinge and axial plane are making zero degrees?
Yes Gurmeet, in case of symmetrical fold axial plane is vertical and angle between axial plane and hinge line is zero i.e. they both are parallel.
