# Regular polygons in space: isopolygon

### 14.9.2 Regular polygons in space: isopolygon

See Section 13.10.2 for regular polygons in the plane.

The isopolygon command creates regular polygons in space.

- isopolygon takes four arguments:
  - A,B,P, three points.
  - k, an integer.
- isopolygon(A,B,P,k) returns and draws a regular polygon with one edge AB in the plane ABP with |k| sides. If |k| is positive, then the polygon is positively oriented, otherwise it is negatively oriented.

#### Examples.

- Input:

  A:= point(0,0,0);
  B:= point(3,3,3);
  P:= point(0,0,3);
  isopolygon(A,B,P,5)

  Output:
- Input:
  isopolygon(A,B,P,-5)
  Output:
