What is a pyramid in math?
In mathematics, a pyramid is a 3D figure built with a base of a polygon and triangular faces all connected together. A pyramid connects each edge of the base to a common tip or apex giving it the typical shape. Let us learn more about pyramids in this section.
What is the name of the 3D polyhedron with the base of a polygon?
A pyramid is a 3D polyhedron with the base of a polygon along with three or more triangle-shaped faces that meet at a point above the base. The triangular sides and the base are called the faces and the point above the base is called the apex. One of the most famous real-life examples are the pyramids of Egypt.
How to tell if a pyramid is right or oblique?
The location of the apex or the top of a pyramid decides whether a pyramid is a right pyramid or an oblique pyramid. A pyramid is named as a right pyramid when the location of the apex is exactly over the middle of the base of the pyramid. Whereas, when the location of the apex is not exactly over the middle but slightly away, then that pyramid is called an oblique pyramid. In other words, when a perpendicular line from the apex intersects the centre of the base, it is a right pyramid. When it does not intersect the centre of the base, it is an oblique pyramid. Observe the following figures to see the difference between an oblique pyramid and a right pyramid.
What is the shape of a pyramid called?
