It is called the base.
any face that is not a base is?
Apex.
A triangular-based pyramid, also known as a tetrahedron, has six lines of symmetry. Each line of symmetry can be drawn from a vertex of the triangular base to the opposite face, as well as along the medians of the triangular base. This symmetry reflects the pyramid's regularity and equal edge lengths in a regular tetrahedron.
A cone has 1 face, 0 edges, and one vertex. The face is the circular flat area. The cone can roll, so it has no edges. Edges have to be straight. The vertex is the pointy thing opposite to the face.
there is one square face, and then four triangular faces that join at the vertex.
Lateral Face - In a prism, the faces that are not bases. In a pyramid, faces that intersect at the vertex.
any face that is not a base is?
a pyramid
Apex.
A polyhedron of which one face is a square, and the other faces are triangles with a common vertex.
Pyramid
Edges: 8 Faces: 5 Vertices: 5
A square pyramid! The base of the pyramid is a square and it has four trianglular faces that meet at the vertex of the pyramid.pyramid
