If the tent has a square base, it is a pyramid.
postulates cannot be proved, they are the base of geometry and there isn't anything to prove it with. if the postulates were wrong then all of euclidian geometry would be wrong. that is like saying how do we know the English language is correct, it is the basis for communication and if it wasn't, then how would speaking the language work?
Euclidean geometry, non euclidean geometry. Plane geometry. Three dimensional geometry to name but a few
There are different kinds of geometry including elementary geometry, Euclidean geometry, and Elliptic Geometry.

A pyramid has a square base.

Base of a trapezoid is a geometry term. It starts with the letter b.
If the tent has a square base, it is a pyramid.
the parts of the cylinder are the base and axis
Many police diagrams are created and recorded using triangulation or base line mapping. Both require geometry.
All artists use geometry, tattoo artists included. Any peice of work that involves straight lines, square/rectangular boxes or circles at the base of the design will involve geometry.
A meter is a unit of measure. It is part of the metric system and the base unit.
The IF4- ion has a square pyramidal molecular geometry with the iodine atom at the apex and the four fluorine atoms at the base vertices.
You'll need it up until calculus. It's a base.
