A cone.
A cone.
a square* * * * *A square does not have only 1 vertex: it has 4.The correct answer is an infinite cone.
If you mean 1 flat surface and 1 vertex, then the only thing I can think of is a cone.
It is (-1, 3).

If a figure has line symmetry about the y-axis, then for every point (x, y) on the figure, there is a corresponding point (-x, y). Given that one vertex is at (-1, -3), its symmetric counterpart across the y-axis would be at (1, -3). Thus, the coordinates of another vertex of the figure are (1, -3).
A cone only has 1 vertex because it only has one point where it connects. (vertex=a point)

There is no such shape.
You're probably thinking of a cone. There is some disagreement as to whether the point of a cone qualifies as a vertex.
