Where do you find vertices?

If a point on the figure is not the intersection of two or more line segments, then it is just a point and not a vertex. It could be a part of an edge or a face, but it does not represent a corner.

Understanding the fundamental elements of a solid is crucial in geometry and 3D modeling. Identifying vertices, edges, and faces is a fundamental step in this process.

Edges, on the other hand, are the line segments that connect vertices. They form the boundaries of the faces and give the solid its shape.

A vertex, or a corner, is a point where two or more line segments intersect. In a solid, a vertex is typically where edges meet, forming a sharp point.

Faces are the flat surfaces of the solid. They are bounded by edges and contain vertices at their corners. The number of faces, edges, and vertices in a solid can vary depending on its shape and size.
