(Jump to Area of a Rectangle or Perimeter of a Rectangle) A rectangle is a four-sided flat shape where every angle is a right angle (90Â°). Opposite sides are parallel and of equal length (so it is a Parallelogram).
A rectangular pyramid has a rectangular base and four triangular sides that meet at an apex. If the pyramid is a right pyramid, then the apex is located above the center point of the rectangular base. The rectangular base has four corners, which means that it has four vertices. At the apex of the pyramid, the four triangular sides intersect and create another vertex at the apex. A rectangular pyramid therefore has a total of five vertices.
