How do I remove all loose edges?

Question

I have cut a hole in a plane, but I am left with some loose edges.

Is there an easy way to select and delete them all?

See this screenshot:

See this edges siting out with no face?

Answer 1

Select the vertex and the end of one, then press ShiftG> Amount of adjacent faces:

Then delete. (Delete> Vertices)

Answer 2

Select the menu item Mesh -> Cleanup -> Delete Loose, options for verts/edges/faces.

Blender 2.70 and later.
