Tangent arcs

This should be simple: I’d like to create a series of tangent arcs. Here’s a picture…

This is just the beginning jig for some forms I’d like to create. Should be straight forward, right? Any help is appreciated.

Here is a quick GH solution that should give you good idea about how to deal with this problem.

Here is another example using the Grasshopper Bi-arc component.

Thank you both for your help! Given that I’d like to not draw any geometry directly in Rhino, I think the bi-arc component solution will give me what I want in this case.

Thanks Rajaa & Scott, both definitions will come in handy. I was looking for arc tangent with Grasshopper a while ago.
