Which of these shapes is a pyramid?
A pyramid will have sloped edges coming to a point. It will have one rectangular or triangular base. This first blue shape we can eliminate because it’s a cube. It doesn’t have sloped edges coming to a point, and has many bases. The third shape we can eliminate because it’s a cone. While it has a sloped edge coming to a point, it doesn’t have a rectangular or a triangular base. It has a base that’s a circle. Therefore, this shape would be our pyramid.
