Although there is some controversy regarding what constitutes ideal posture of the pelvis in the sagittal plane, it is generally considered to be a position of anterior tilt such that the sacral base angle measures approximately 30 degrees.
As anterior pelvic tilt and therefore the sacral base angle increases, the lumbar spine must compensate by commensurately increasing its lordosis; similarly, if the sacral base angle decreases, the lumbar spine compensates by decreasing its lordosis (Figure 3).
Shappy believes that any bullet base angle
that isn't 90 degree to the longitudinal axis can be inaccurate.

The triangles AEB and FEB are clearly congruent, because they have two base angles
and the included side BE equal in each.
To prove that base angles of an isosceles triangle are equal becomes the work of a moment.
The property that isosceles base angles are equal will fall out as a corollary.
