As per the Euclidean geometry, a set of points are considered to be collinear, if they all lie in the same line, irrespective of whether they are far apart, close together, form a ray, a line, or a line segment.

First, from 1999, we have a question about the words “necessary” and “sufficient” in the statement of a theorem to be proved; such a statement is also called a “biconditional”, as we have conditions in both directions. The geometrical theorem here is simple, probably intended just to demonstrate the form of … See more Adeel asked about these words in 2002: I used an example (unlike Abdellah’s question above) in which only one part is true, which makes it a little easier to see the distinctions: I needed a different example to illustrate … See more I think some additional explanation is needed for the meaning of “only if”; but I couldn’t find a good discussion of this in the archive.

WebSo, if two chords are given with the same lengths L, then from equation (1) the are equally remoted from the center. And vice versa, if two chords are equally remoted from the center, then the formula (1) shows that in this case their lengths will be the same. So, this statement is proved. Hence, the only step to do is to check that the chords ...
