Angles met obliquely in parts (9)

I believe the answer is:

segmental

'in parts' is the definition.

'angles met obliquely' is the wordplay.
'obliquely' indicates anagramming the letters (oblique can mean unusual or unexpected).
'angles'+'met'='anglesmet'
'anglesmet' is an anagram of 'SEGMENTAL'.

(Other definitions for segmental that I've seen before include "Composed of distinct parts" , "As, say, Orange" .)

I've seen this clue in The Guardian.
