triangle
it is a three dimensional cone , the circle is the edge of the figure and the curved side is the body of the cone, the vertex is the point of the cone
The side of a cone is - not surprisingly - conical is shape. Its net is a sector of a circle.
A cone has one side, the bottom surface, but not all cones have this surface. They may also be considered to have 'an inside' and 'an outside', which would be two sides. But as a relative of the circle, a cone has mathematically infinite sides.

parasite or secondary cone
A cone has one side, the bottom surface, but not all cones have this surface. They may also be considered to have 'an inside' and 'an outside', which would be two sides. But as a relative of the circle, a cone has mathematically infinite sides.
the cone has three sides
a parabola
The cone IS a 3d figure.
Triangle
Tilt of cutting plane is between (perpendicular to axis of the cone) and (parallel to the side of the cone).
An Apex or Vertex of the cone
A cone has one side. (The bottom) Because the other surface is curved, it does not count as a side. It is the same concept as a sphere.
