Talk:Subtended angle

Okay, I think it means...

An angle opposite a curve, used to create a triangle of sorts, with the curve in the place where a straight edge would be in an actual triangle...

It's a question. Is this what that means? ~ R.T.G 11:11, 18 September 2019 (UTC)Reply

The angle opposite the curved edge, in a triangle with two straight edges and one curved edge...? (EDIT:also asked to reference desk just now) ~ R.T.G 11:12, 18 September 2019 (UTC)Reply

No encyclopedic coverage

This article seems to run afoul of the policy that Wikipedia is not a dictionary, in that it simply defines what a subtended angle is and provides no encyclopedic coverage. This page seems to do little more than a dictionary definition could. However, it doesn't seem that much can be done about this, given that there isn't exactly a rich history of subtended angles or some other information that could give the article encyclopedic coverage. I originally considered nominating the article for deletion but wanted to check on the talk page for what other people seem to think. Rappatic (talk) 00:16, 29 July 2021 (UTC)Reply

Possible examples:
  • a parsec is defined as the distance the at which the mean radius of the earth's orbit subtends an angle of 1 arcsecond.
  • the apparent size of an object is determined by the angle it subtends at the eye.
  • total and annular solar eclipses occur as they do because the moon and sun coincidentally subtend almost exactly the same angle at the earth's surface.
  • Subtended Angle Theorem: at any point on the circumference, a circle's diameter subtends an angle of 90°.
  • An arc of a circle subtends double the angle at the circle's centre that it does anywhere on the remaining part of the circle.

An angle is subtended at a point, not subtended from, so the image is wrongly worded. Musiconeologist (talk) 17:54, 9 September 2021 (UTC)Reply
