The fixed point at the intersection of all the faces of the pyramid is called the VERTEX of the pyramid.
A hexagonal pyramid has 6 triangular faces that meet at a point. It has 6 triangles and 1 hexagonal base.
A square pyramid is a polyhedron with a square base and triangular sides that meet at a point at the top. This gives this pyramid five faces.
pyramid
4 sided (or perhaps 5 if you count the base). The base is a square and the four triangular faces rise off each of the 4 edges and meet in a point at the top.
There is no specific name for lines that meet at one point, but lines that meet at a point, the point is called the intersection point.
A pyramid would fit the given description
The flat surfaces on a pyramid are called faces. A pyramid has one base and triangular faces that meet at a single point called the apex. On a cube or rectangular prism, the flat surfaces are called faces as well. But unlike a pyramid, a cube has six square faces, while a rectangular prism has two rectangular bases and four rectangular faces.
a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point
A hexagonal pyramid has 6 triangular faces that meet at a point. It has 6 triangles and 1 hexagonal base.
A square pyramid is a polyhedron with a square base and triangular sides that meet at a point at the top. This gives this pyramid five faces.
A solid figure with a polygonal base and triangular faces that meet at a common point.
The description given fits that of a pyramid
That sounds like a square-based pyramid.
A pentagonal pyramid.
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!
pyramid
They are the one dimensional "lines" where the faces of the pyramid meet, in pairs.
