Line segments in the plane

### 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).

#### Example

segment(-1,1+i)

or:

segment(point(-1),point(1,1))

or:

Line(-1,0,1,1)
