A cone has one vertex and one edge.
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.
depends on what shape that vertex is in
There are infinitely many shapes. Among them are polyhedra, with four or more vertices.
c
A polygon.
L shape
all of the shapes
triangle * * * * * A triangle is NOT a 3d shape! A cube.
A triangle for example has 3 vertices.
The 2-dimensional shape with one more vertex / side is a decagon.
A cuboid.
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.
A diagonal in a shape is a straight line from one vertex to another vertex (corner).
A cone has one vertex and one edge.
Almost any 2D/3D shape has more than one vertex. Triangles, squares, rectangles etc. etc.
An incomplete shape.
