An edge.
An edge.
An edge.
One side or edge times another. (length x width = area)
you call it a edge
ffgfgghghhh
Possibly a face - or an edge. It would help if the question was properly phrased.
A place where two faces meet is called an edge.
A cone has one face and one edge.
A cone has only one edge simply because it only has one face. Although one face may have several edges, a circle is a closed figure with only one vertice, resulting in one edge. The rest of the shape is 3-D, but with only one face, there is an infinite amount of points on a cone. The cone joins on another vertice, but since the face is a circle, there is still only one actual edge. Thus, there is only one edge on a cone because there is a single, circular face.
The edge should face away from the plate.
A cone only has one edge simply because it only has one face. Although a face can have multiple edges, in the case of a cone, which has a circular face, it only has one edge because the face is a closed figure; namely, a circle. The rest of the figure is still 3-D, but since there is only one face, there are an infinite amount of spaces in the area between the edge and the vertice, resulting in an area, not an edge. The contracting circle joins at a vertice parallel to the face. This vertice does not compute as an edge either because there is only one circular face. Thus, a cone has one edge because it has only a single, closed face. By: Brian Jiang (seriously though, Steven, Ubi, Liam, Malcolm, Moshina, etc.
