Hi there,
Question for anyone out there......
In our school we have just purchsed MicroWorlds Robotic EX
for Windows XP. I have used the more basic MicroWorlds Logo
software before and am vexed by the following.
In the basics programming mode, a user can write a
procedure for a regular polygon taking in consideration
that the number of sides that polygon has relates to 360
degrees.  A procedure for a pentagon would write like this:
to pentagon 
repeat 5 [fd 50 rt 360 / 5] 
end 
It also could be written as follows, depending on whether
you wanted to have the computer do the math for you:
to pentagon
repeat 5 [fd 50 rt 72] 
end 
In probing why the number of sides relates to the angles
(having to add up to 360) what angles are refered to? I am
wanting to know why this is so. 
I have heard this refered to as Total Trip Theorem.  Can
anyone shed some light on this?
Thanks
Jen
