About halfway up, however, the angle of incline decreases from over 51 degrees to about 43 degrees, and the sides rise less steeply, causing it to be known as the Bent Pyramid. The change in angle was probably made during construction to give the building more stability

Yes, the bent pyramid, but that say nothing, maybe simply a design of an bad architect. They always exist, even today.
