Inkscape – Draw path tangentially to an endpoint of a curve

Okay so say I have a shape like this:

Inkscape shape showing path selected

Now I want to snap a new path to one of the corners and then extend it tangentially from the curve.

Extending path from previous shape
(This, but snapped to the tangent)

How do I do this? I know how to snap a line from an arbitrary point to a tangent of a curve but that doesn’t exactly help when the start node of the line is one of the endpoints of the curve itself. But surely it’s possible? I mean, you have the tangent at that point right there in the handle of the curve…

Answer

Here’s a method that should give you an accurate result, with no guessing or eyeballing.

  1. Select the shape, and do Extensions > Visualize Path > Draw handles.

enter image description here

  1. Select the drawn handles and do Object > Objects to Guides, or Shift+G

enter image description here

  1. You can now use snapping to guides and cusp nodes to draw your new line. The Bézier handle will snap to the guide so you can match it with the angle of the Bézier handle of the original shape.
