Measurements - Need some help

[Fonte Boa]

Hi, Paul.

Since Rotate to Target command wont work to solve this situation, i would like to try the trig via.

Draw both vertical bits (side view)
Find the centre of the (air) gap between them (draw 2 diagonals)
Draw a circle, of diameter the same as the width of the blocks (2 units here) with its centre on point just found.
If you now draw lines from the relevant block corners, tangential to the circle

I tried to reproduce these steps by eyeball and reached the following situation:



But i didnt understand what i have to do from this point ("draw lines from the relevant block corners, tangential to the circle").

I delete one of the diagonal lines and crease the other trying to make the new ones just touch in a single circle point each one. For sure this isnt the correct result:



Drawing in Photoshop as you described above ("draw lines from the relevant block corners, tangential to the circle"), the result was the following (that seems correct):



So the question is:
which Wings tools should i have to use to produce this last result?
if Tools|Connect is the way, how can i draw those 2 diagonal edges making them TANGENT the circle?
