Euclid ProgramΒΆ
- To join two points with a line, I actually set the Turtle on a point, set its heading (the direction it was pointing) and sent it off in that direction both to draw the second point and to draw the line joining the points.
- To extend a line, I drew it, and then told the Turtle to go forward in the same direction.
- To draw a circle, I put the Turtle at the outer end of the line, and told it the radius length.
