acute angle

This and reflex angle and obtuse angle were all deleted 4 years ago. The discussion that was had was, IMHO, somewhat weak, and perhaps a fresh discussion is needed to restore these terms. --Type56op9 (talk) 17:49, 27 September 2014 (UTC)

Why is it not covered by sense 4 of acute? I suppose we have acute triangle, so we should be consistent. Dbfirs 18:15, 27 September 2014 (UTC)

• Restore both as set phrases: the definitions of "acute" and "obtuse" that apply to angles are not the most common definitions of acute and obtuse. Purplebackpack89 21:34, 27 September 2014 (UTC)

Everyone apparently wanted to keep prime number (a number that is prime), and this seems entirely analogous. But my view is delete as SoP, or redirect to "acute" etc. Equinox ◑ 00:24, 28 September 2014 (UTC)

• Keep (restore) "acute angle" and "obtuse angle", now as before per talk:free variable: "acute" in that sense predominantly applies to angles; for the previous RFD discussion, see Talk:obtuse angle#RFD. Let me note that "acute angle" is at AHD[1], Collins[2], and Macmillan[3]. Furthermore, whether Talk:obtuse_angle#RFD was closed regularly is questionable, IMHO. --Dan Polansky (talk) 07:42, 28 September 2014 (UTC)

  Keep reflex angle as well; “reflex angle”, in OneLook Dictionary Search. shows it in AHD and Macmillan. --Dan Polansky (talk) 19:14, 30 September 2014 (UTC)

• Restore and keep. --Anatoli T. ^{(обсудить}/^вклад) 23:41, 28 September 2014 (UTC)

• 'Keep. Obviously, this term belongs to the mathematical vocabulary, it's a term of the language. Lmaltier (talk) 17:50, 10 October 2014 (UTC)

Kept. bd2412 T 20:24, 23 October 2014 (UTC)
