It is a tetrahedron which is a triangular based pyramid having 4 faces, 6 edges and 4 vertices
A triangular based pyramid has 4 faces and 4 vertices
Assuming that a solid triangle is a tetrahedron, the answer is: faces: 4 edges: 6 vertices: 4
A triangular based pyramid seems to fit the description which has 4 faces, 6 edges and 4 vertices
None. Using Euler's formula v - e + f = 2, where v is vertices, e is edges, and f is faces, we see that for your question f = 3. No solid figure can have less than 4 faces (a tetrahedron).
