It is called a vertex.
Well, honey, the shape you're looking for is a "hexagonal prism." It's got more than one vertex and an "E" smack dab in the middle. So, go ahead and impress your friends with that little nugget of geometry trivia.
For two dimensional shapes, a vertex (plural vertices) is a point where two sides meet.For 3D shapes, a vertex is a point where three or more faces meet.
Possibly a cone? No, A cone is one of the few solid objects with one vertex. A pyramid (which includes a tetrahedron) has 4 or more. A prism (which includes a cube) has 6 or more (but even numbers only). Other regular solids are octahedron (6 vertices), dodecahedron (20), icosahedron (12).

triangle * * * * * A triangle is NOT a 3d shape! A cube.
Any polyhedron.
A cuboid.
Rhomboid
I think this means, what is the plural of vertex?? If so, then the answer - vertices. My daughter and I searched for ages thinking the question was looking for the name of a 3d shape!!
Almost any 2D/3D shape has more than one vertex. Triangles, squares, rectangles etc. etc.
There are infinitely many shapes. Among them are polyhedra, with four or more vertices.
3d shapes with plane faces are called polyhedra (singular = polyhedron). The minimum number of vertices is 4, there is no maximum.
cylinder defenly * * * * * Whatever defenly means, the answer is definitely not a cylinder which has no vertex - not more than one! A rhomboid is one possible answer.
is it a vertex
Vertex.
The question is not particularly clear but I suspect that the answer is a vertex.
