vertexes
One whose boundaries are straight lines.
... are straight lines where two planar surfaces meet.
it if called a edge for a 3D shape
Using the definition for corner of the place at which two converging lines or surfaces meet. There are 30 edges or corners to an icosahedron. * * * * * Normally, a corner of a solid shape is understood to be a vertex - not an edge! An icosahedron has 12 vertices.
Angle is a space between two lines or surfaces that meet at one point, which you measure in degrees.
A rhombus is a quadrilateral. It has four sides. We usually think of edges as the line along which two surfaces of a solid meet.
Venus and Mercury also have solid surfaces.
No, "corner" is not a preposition. It is a noun that refers to the point at which two lines or surfaces meet. Examples of prepositions include "on," "in," "under," and "between."
The point where two surfaces meet is called an "intersection" or a "junction."
Lines that meet are not parallel, and parallel lines never meet.
A solid figure with 2 flat surfaces and 0 vertices is a cylinder. A cylinder has two circular flat surfaces, known as bases, and no vertices because it does not have any corners or points where edges meet. It is a three-dimensional shape that is formed by a curved surface connecting the two bases.
Parallel lines meet in infinity(they don't meet at all)
