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.
There are a great many of them. One nice one is the icosahedron, which has 20 vertices and 11 letters.
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.
A point where three (or more) faces (sides) meet.
The concept of a vertex, which is the intersecting point between two or more geometrical shapes, is meaningless in this case. A point can't have a vertex since it has no shape. A vertex, however can be a point. For example, if one 2-D line intersects another 2-D line, that point of intersection is the vertex.
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 polyhedron.
all of the shapes
