Triangular pyramid.
A shape with four sides and three vertices does not exist in Euclidean geometry. In Euclidean geometry, a shape must have the same number of sides as vertices. Therefore, a shape with four sides would have four vertices.
There is no such shape. The only convex shape that has four faces is a tetrahedron, and that has four vertices, not 5.

square-based pyramid
pyramid
A pyramid BK
Triangular pyramid.
There is no solid shape with exactly four squares and no other faces.
A shape with four sides has four vertices and a shape with three sides has three vertices, so a shape with four sides has more vertices than a shape with three sides.

A triangular based pyramid has four vertices and four faces
The shape that has 4 vertices, 4 faces, and 6 edges is a TetraHedron. ---- A tetra-hedron is a four sided triangular prism, that is a prism or solid that has four faces each one a triangle. Tetra is the Greek word for the number four. Hedra is the Greek word for side.....

A tetrahedron, otherwise known as a triangular pyramid, has four faces, four vertices and six edges.
