Euclidean geometry may be taken as a set of axioms. This I take to be your 
view.

I take a somewhat different approach to both Turtle and Euclidean (plane) 
geometry.

Turtle geometry is a representation, using the computer as a medium, of 
the process of using a (numerically graduated) ruler and protractor to 
draw a path. Paths so drawn may have the appearance of classic Euclidean 
forms when looked at, on completion, on either paper (floor Turtle) or 
screen. Turtle geometry is capable of representing a range of path making 
processes, including pursuit. 

Geomland is a representation, using the computer as a medium, of the 
process of using a straightedge and compass to construct a variety of 
geometric forms consisting of lines and arcs. In this geometry it is 
possible to represent mechanisms. That is, it is possible to describe a 
general procedure for a lever.
