26.6.3  Line segments in the plane

See Section 27.4.3 for segments in space.

The segment command draws line segments. (The segment command can also draw vectors (see Section 26.6.4.)

• segment takes two arguments: P,Q, two points (which can also be given as a list).
• segment(P,Q) returns the corresponding line segment and draws it.

The Line command also draws line segments, but with a slightly different syntax.

• Line takes four arguments: a,b,c,d, four real numbers.
• Line(a,b,c,d) returns and draws the line segment from (a,b) to (c,d).
