GENERAL KNOWLEDGE

Detailed explanation-1: -Most pyramids were built to correspond to cosmological principles, such as astronomical orientation. They also represented the recreation of an axis mundi, a world axis where the pyramid became the cosmic center around which the rest of the universe revolved both vertically and horizontally.

Detailed explanation-2: -Mesoamerican cultures never invented the keystone, and so were unable to build true arches, but instead, all of their architecture made use of the “false” or Corbelled arch. These arches are built without centering and can be built without support, by corbelling regularly the horizontal courses of the wall masonry.
