The description given fits that of a pyramid
it is a triangular pyrimid
A pyramid.
A solid figure with a polygonal base and triangular faces that meet at a common point.
A triangular prism has 4 triangular faces and 6 edges (3 for the base and other 3 to form the "point" of the pyramid.
A tetrahedron (triangular pyramid).
a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point
they are both types of pyramidsThey're both triangular pyramids, and all of them have a base, multiple faces, and at one end the faces come to a point.* * * * *They are NOT both triangular pyramids!
The shape you are describing is a triangular pyramid. A triangular pyramid has a base that is a triangle and three triangular faces that meet at a single point called the apex. The base of the pyramid is a rectangle, which is a quadrilateral with four right angles. The triangular faces of the pyramid connect the vertices of the base to the apex.
a pentagonal pyramid it has five triangular sides that all meet at a point at the top. the base is a pentagon
A triangular pyramid. This is one where all the faces are triangles - a three-sided base, from which three triangular faces rise to a single point - the apex.
quadrilateral is a polygon with four sides or edges and four vertices or corners A pyramid is a solid figure with a polygonal base and triangular faces that meet at a common point. So no.
A pyramid. But the point where the triangular faces meet is a vertex, not a vortex. A vortex is a spinning mass of fluid like a whirlpool!
