This is a possible solution, but I don't think it is the best way.



Add names for the circles.

node[state] (b1) [below =of a1]{};
node[state] (c1) [right =of a1]{};
node[state] (d1) [below =of c1]{};
node[shape=circle, draw=black, minimum size = 4cm, fit={(a1)(d1)}] (circle1) {};
node[state] (a2) [right=7cm of a1] {};

    I think the OP is looking for tangents on these circles and not to connect their north points... if for example the right circle was smaller this solution would not give a nice result.

  • @koleygr Indeed from the attached figure we can't say if the OP wants to join the two norths or have a tangent line. I thought of that too, and that is why I said "but I don't think it is the best way". If the OP explains his question further, I will be very glad to delete my answer.

AFAIK the first way to draw a tangent at two circles has been proposed in this nice answer. However, can't refrain from using this one.



documentclass[tikz,border=3.14mm]{standalone}

n3={atan2(#4-#3,n2)}
in ($(#1)+(n3+n1+90:#3)$) -- ($(#2)+(n3+n1+90:#4)$)}},-latex ,auto ,node distance =0.8cm and 0.8cm ,on grid,
thin , state/.style ={ circle ,top color = black, bottom color = black,
draw,black , text=black, minimum width =0.01 cm}]
node[state] (a1) {};
node[state] (b1) [below =of a1]{};
node[state] (c1) [right =of a1]{};
node[state] (d1) [below =of c1]{};
node[shape=circle, draw=black, minimum size = 4cm, fit={(a1)(d1)}]
(circ1){};
node[state] (a2) [right=7cm of a1] {};
node[state] (b2) [right =of a2] {};
node[state] (c2) [below =of a2] {};
node[state] (d2) [right =of c2] {};

    This is a possible solution, but I don't think it is the best way.



    Add names for the circles.



    documentclass[tikz,margin=3mm]{standalone}
    usetikzlibrary{positioning,fit}
    begin{document}
    begin {tikzpicture}[,auto ,node distance =0.8cm and 0.8cm ,on grid,
    thin , state/.style ={ circle ,top color = black, bottom color = black,
    draw,black , text=black, minimum width =0.01 cm}]
    node[state] (a1) {};
    node[state] (b1) [below =of a1]{};
    node[state] (c1) [right =of a1]{};
    node[state] (d1) [below =of c1]{};
    node[shape=circle, draw=black, minimum size = 4cm, fit={(a1)(d1)}] (circle1) {};
    node[state] (a2) [right=7cm of a1] {};
    node[state] (b2) [right =of a2] {};
    node[state] (c2) [below =of a2] {};

      I think the OP is looking for tangents on these circles and not to connect their north points... if for example the right circle was smaller this solution would not give a nice result.

    • @koleygr Indeed from the attached figure we can't say if the OP wants to join the two norths or have a tangent line. I thought of that too, and that is why I said "but I don't think it is the best way". If the OP explains his question further, I will be very glad to delete my answer.

      This is perfect. I just want lines to show that circle on the right is a subset of the circle on the left. Thank you! Will accept asnwer in 2mins when it lets me.

      Wow... I was almost ready to insist that even without a clear question about these tangents it still seems a clear expectation to me... Nice guess (+1)

    AFAIK the first way to draw a tangent at two circles has been proposed in this nice answer. However, can't refrain from using this one.
