A 3D shape with one vertex is called a cone. It has a circular base and a single apex (the vertex) where all the lines from the base converge. The shape tapers smoothly from the base to the vertex, creating a pointed top. Other examples of shapes with one vertex include certain types of pyramids, but cones are the most common reference for this characteristic.

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
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!!
A cuboid.
Rhomboid
The question is not particularly clear but I suspect that the answer is a vertex.
