An edge. A horizontal edge, to be more precise.
Perimeter
A circle or an oval! (: * * * * * No. A circle or oval has a face and an edge. The correct answer is a point.
Yes. I think of an edge as a line. The edges meet at vertices, and the faces meet at edges.
One possibility is a cylinder whose bases do not stop in edges but flow gradually into the length of the cylinder.
nonagon
A geometrical construction can be made with with a straight edge and a compass.
A construction. A construction is a geometric drawing of a figure usually made by a compass and/or a straightedge
Geometric figures can be drawn using a compass and a straight edge. This is commonly known as ruler and compass construction.
The line that forms the edge of a figure is an edge line. Which forms the figure the has been drawn. You use this line to define a drawing or a figure.
A straight edge
A ruler can be classed as a straight edge.
An edge. A horizontal edge, to be more precise.
A side is basically a geometric shape; and edge is where two sides met.
There are no regular geometric figures with 9 edges and 10 faces.. I'm not even entirely sure there is an irregular geometric figure that would allow for such a combination- edge count and face count are usually identical... Maybe if you were describing some sort of conic section but I can't figure out what that might look like.
circle
An edge of a 3 dimensional figure
