In terms of LOGO it means that circles of any diameter, radius
or circumference can be drawn. Consider the following
procedure:
TO CIRC :C
REPEAT 360 [ FD :C/360 RT 1]
END
What do you think this is about?
Once decided, trace the procedure through in your mind's
eye.
If you can, talk to others about what you think is happening.
If in doubt out check your thoughts by typing in the procedure
and testing what it does. N.B. Pi is a primitive approximately
equal to3.14159.
Try CIRC 314
For now experiment by changing:
The number of times you repeat the instruction (360) Or the
length of the circumference (:C) Or the amount of turn done
after each forward movement (1 degree)
Alternatively you might like to consider the next
procedure:
TO CIR :D
REPEAT 360 [FD :D*PI/360 RT 1]
END
Try the following CIR 100
What do you notice now?
