You can draw a tangential circle given (2 circles + 1 line).

Try main menu: Draw -> Circle -> Tangential 3 Circles

it says "3 Circles", in the sense of generalized circles: http://en.wikipedia.org/wiki/Generalised_circle

At each step, you can select either a line or a circle.

This "3 Circles" could be buggy due to limited robustness of our equation solver, but we can keep improving it.

Ah, well - here is the curve I'm trying to achieve:

So I have an arc attempting to connect the two circles and the 73deg line, and I'd like to be able to adjust the oval's orientation to get the desired curve - then trim down the curve so that it ends at the tangent point against the middle most circle. Any advice on getting this curve to meet the straight line and the two circles?
Thanks
