How do I control the curvature of an arc

Hi, I have 3 points, A, B, and C, I want to make 2 arcs, one from points A and B, and the other one from points B and C. I have the arcs, but is there a way to control the curvature of the 2 arcs so that they look similar to the ones in the pictures I attached. 

Thanks
Yan

Well, I'm told the assignment deadline has well and truly passed, so I've posted my Grasshopper definition (using Geometry Gym Components) at modelling this truss. You can download the definition from http://geometrygym.blogspot.com if you wish to study it.

Cheers,

Jon
