a circle ??
semi circle
A cone perhaps?
its a lens...1 curved edge = a circle, 1 flat surface = back, 1 curved surface = front. (these are used in some battery-less flashlights, as an example.)
A shape with 1 vertex, 1 edge, 1 flat face, and 1 curved face is a cone. The vertex is the tip of the cone, the edge is the circular base where the flat face meets the curved surface, and the flat face is the circular base itself. The curved face extends from the base to the vertex.
A cone would fit the given description

A cone would fit the given description
The shape you are describing is a cone. A cone has one flat circular base (which can be considered as having one edge), one curved surface that wraps around the base, and one apex or point at the top. Thus, it fits the criteria of having one edge, one curved surface, and one point.
A semicircle is one shape fitting this description.
