A cone has one circular base and a vertex that is not on the base.as described on math.com
If you mean "How many diagonals can be drawn from one vertex of a figure with 16 sides", the formula is n-3, where "n" being the number of sides of the figure. So 16-3 = 13 diagonals that can be drawn from one vertex.
a cone
true
vertex
Because the base of a cone is round, it is the only three dimensional figure with only one vertex.

a cone
A conic section.
There are 19
There two different shapes that have more than one vertex. One is a triangle it is a plane figure that has three straight sides and three angles and a quadrilateral which a four sided figure.
It is (-1, 3).
