Attached is one way to do it, using an xprod you can have the perpendicular vector, and then all you have to do is add an SDL line.
Is that right?

Thanks Carlos: that certainly gives me a starting point. I'll play around with it.

I generated my arc using Radians and a radius but your solution should work just fine.

 I had not thought to use vector products, rather I was trying to do this as I would have done in native Rhino using "line perpendicular from a curve" but could find no way to access that from GH.

much appreciated

Using the Radius/Angle component.

Thanks Chris:  more elegant than my attempt.
