'fish' is the definition.
(angle can mean to fish)

I cannot understand how the rest of the clue works.

(Other definitions for angle that I've seen before include "Fish with a rod" , "Point of view - associated with Saxon" , "Glean (anag.)" , "that is often right" , "Perspective" .)

I've seen this clue in the Sydney Morning Herald.
