For centuries after their discovery, the trigonometric functions—of which the most familiar and fundamental are those known as the sine and cosine—were closely associated with the properties of triangles.

The Egyptians developed practical knowledge of arithmetic, algebra, geometry, and trigonometry.

pyramid, in geometry, solid figure bounded by a polygon (the base, or directrix) and the surface generated by a moving line (the generator) passing through a fixed point (vertex) and continually intersecting the perimeter of the polygon.

A pyramid is an artificially made geometric solid of the shape made famous by the royal tombs of ancient Egypt. It is a solid with a base of a three-sided or foursided polygon (trilateral or quadrilateral, respectively) and whose lateral faces are triangles (trilateral sides) with a common vertex (the vertex of the pyramid).
