That 3D shape is called triangular pyramid.
They are called a Vertices and it is where 2 edges meet.
# of faces + # of edges + # of vertecies + 2
It is a triangular prism that has 6 vertices, 9 edges and 5 faces.
According to Euler none; for all 3d shapes: Vertices + Faces = Edges + 2 ⇒ 12 + 8 = 19 + 2 ⇒ 20 = 21 So unless 20 does equal 21, no 3d shape has 8 faces, 19 edges and 12 vertices. Any 3d shape with 8 faces would be an octahedron.
