a square* * * * *A square does not have only 1 vertex: it has 4.The correct answer is an infinite cone.
cone
Cone
A cone
a oval or heart
A cone.
Yes, the point on the cone is a vertex.Typical math textbooks define a cone as "A solid figure with one circular face and one vertex." So yes, there is one vertex.
If you mean 1 flat surface and 1 vertex, then the only thing I can think of is a cone.
no solid figure has only face the only shapes that has 1 face is 2d shapes
It is (-1, 3).

This is an impossibility. If it is a solid figure then it will have more than 1 surface. If it has only 1surface and it is a solid, then it must be a sphere, but the surface of a sphere is not flat is it? By using the word 'solid' then by definition, it is three dimensional and has thickness. A cylinder has no vertices , but it has 2flat surfaces. A vertex is a point where three lines meet, such as on a pyramid, which has 4 vertices. Have I forgotten something or is this a 'trick' question?
