I’m looking for a way to construct the line (image attached showing 2 different possibilities) in Tikz without using a node at the junction point of the two line segments (horizontal and diagonal). I can make one of these for each position but would much prefer to use a re-usable solution which would just change: starting and ending position along with angle. Is there something which already does this? Something along the line of balloons for labelling parts in an assembly?
