The description given fits that of a pyramid
A solid figure with five faces is called a pyramid. Specifically, a triangular pyramid, or tetrahedron, has four triangular faces, while a square pyramid has one square base and four triangular faces, totaling five. The pyramid's faces meet at a single point called the apex.
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 solid figure with a pentagon as its base and triangular faces is called a pentagonal prism. In this 3D shape, the two pentagonal bases are parallel and connected by five rectangular lateral faces. However, if you specifically mean a solid with a pentagonal base and triangular faces that converge at a single point, then it is known as a pentagonal 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.
