Finding a internally tangent circle for existing 2 circles.

I was drawing simple things in grasshopper, however couldn't manipulate that "Circle tan tan" or "Circle Tan Tan Tan" components well.

These question makes me feel embarrassed even though i was able to do it in high-school like a decade ago.
Is there any option to make a 3rd circle which is internally tangent to 2 existing circles no matter those 2 intersect or not? Maybe some especial geometry component plug-in could exist already. Could you please share the knowledge, and remind me if you still remember how to find the curve which could be the center of 3rd circle?

Thanks in advance.

Thank you Pieter Sergeren for the component.
I will use your method for complex object, however I've realize it in simple geometry way :) I will construct it in grasshopper on my coffee time~
