2. What is the difference between a right pyramid and a regular pyramid?

If the perpendicular dropped from the base's vertex intersects the base at its center point, i.e. the center of the inscribed or circumscribed circle, the pyramid is said to be the right pyramid. To put it another way, the pyramid's vertex is perpendicular to the base drawn across its center. The pyramid is known as an oblique prism elsewhere.

On the other hand, if the base of a pyramid is a regular figure, all sides of the base are equal, it is considered to be a regular pyramid.
