Hello everyone.

I've been trying to help my nephew with his math quiz from school but it is difficult enough to do in Moi that I can't solve it yet.

So we provided with 3 lines:
- 1 horizontal blue line with length of X√2
- 2 magenta lines with length of X

The task is to arrange them in specific ways so that: they form a continuous polylines with each endpoints are exactly on a perfect circle circumverence (red circle), like in the provided illustration (it's actually not an acurate drawing I made in Moi). The real task is to form a pentagon with 4 magenta lines (length = x) and 1 blue lines (length = x√2), but I believe we can ignore the other 2 since they'll be added later by mirroring the 2 existing magenta lines horizontaly.

It's really difficult to rotate both the Magenta Lines so that they meet the specified condition above!

A friend told me that the problem could easily done with 'constraints' feature, but I REALLY want to solve it just using Moi3D.

Please tell me what I have to do? Thank you very much in advance.
