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.
The 3D shape you are looking for is a "octahedron." An octahedron has eight triangular faces, six vertices, and twelve edges, making it a polyhedron with more than one vertex. Its symmetrical shape is commonly seen in various applications, including crystal structures and dice.
There are a great many of them. One nice one is the icosahedron, which has 20 vertices and 11 letters.
The corner of a 2D shape is called a "vertex" (plural: vertices). A vertex is a point where two or more edges meet, and it is a fundamental element in defining the shape's structure. In polygons, each vertex corresponds to a corner of the shape.
They are the points where three (or more) planes (or faces of the shape) meet.
triangle * * * * * A triangle is NOT a 3d shape! A cube.
Rhomboid
A cuboid.
octahedron * * * * * OCTAHEDRON has 8 letters??? I make it 10. How about TRIANGLE?

polyhedra
Im here to answer your question- possibly a cone. * * * * * and give you the wrong answer. A cone is a shape with 1 vertex: not MORE THAN 1 vertex! All polyhedra have more than 1 vertices.
A polygon.
Nothing. Vertices is the plural term from vertex. A vertex is a point where two or more lines meet. They usually terminate (end) there but don't have to. In a 2- or 3-dimensional shape a vertex is a corner.
They are the points where three (or more) planes (or faces of the shape) meet.

Any 2-dimensional shape has a vertex where two sides meet.Any 3-dimensional shape has a vertex where three or more faces meet.
Any polyhedron.
