Sagot :
Answer:
an edge (of that polygon or polyhedron) if they are adjacent vertices, or a diagonal.
Step-by-step explanation:
when both of the segment's end points are vertices of a polygon or polyhedron, the line segment is either an edge (of that polygon or polyhedron) if they are adjacent vertices, or a diagonal. When the end points both lie on a curve (such as a circle), a line segment is called a chord (of that curve).
Answer:
More generally, when both of the segment's end points are vertices of a polygon or polyhedron, the line segment is either an edge (of that polygon or polyhedron) if they're adjacent vertices, or diagonal. When the end points both lie on a curve (such as a circle), a line segment is called a chord (of that curve).
