I am trying to make a simple wedge shape that is 1/6 of a hexagon.
So I used the polygon tool to make a hexagon. I convert it to a path. I duplicated it, shrunk it down some and used a boolean operation to cut a smaller hex shaped hole in the exact center of the larger hexagon.
Then I used the node tool to select the extraneous nodes and delete them. Now I have two lines, both part of the same path, but not connected. When I select two end points on the lines and try to join them with a new segment, I get an error saying I haven't selected two nodes!!!
What's happening is a bit unintuitive, because the nodes look like end nodes, but aren't. If you have stroke turned on, it looks like two separate subpaths that are just straight lines, each with one node at each end. Why aren't they end-nodes, right?
When you create the donut shape by cutting a hole in the hexagon, you get two sets of nodes: the six around the outer perimeter, and the six around the inner perimeter. Those two sets are disjoint; there are no connections between the outer nodes and the inner nodes. When you delete nodes, the two sets are kept separate. If you delete one node at a time, you can see that at no time is there a connection made between the outer and inner, yet each set is still connected in a loop. For example, delete one of the outer nodes, and the outer perimeter is still a loop, but with 5 nodes instead of 6.
If you kept deleting one node at a time from the outer perimeter until only two were left, you would see just a line between them, and they appear like end-nodes. But there is still a loop! There is a connection from one to the other, and another connection back again. So they aren't end-nodes. You can verify this by click-and-dragging the line between them. It will pull out one of the connections. Then you can remove that connection by clicking on it and choosing the "split path between two non-endpoint nodes" icon on the toolbar. The icon looks like two connected nodes on top pointing to two disconnected nodes below.
Once you do the same to the line formed from the inner perimeter nodes, then you really will have two subpaths with two end-nodes each, and you can join them the way you intended.

...or you can just select both segments, combine them, select both end nodes, then hit your join nodes.
