If a quadrilateral has its vertices on a common circle, then if you multiply the digonals, it should come out the same as if you take one pair of opposite sides, multiply their lengths, do the same for the next pair, and then add them together.

Ptolemy's Theorem states that in a quadrilateral, the product of the two diagonals is equal to the sum of the products of the opposite sides. Mathematically, for a quadrilateral with sides a, b, c, d and diagonals e and f, the theorem is represented as: ef = ac + b*d.

What is the difference between a theorem and a theory?
From Wikipedia:In mathematics, a theorem is a statement proved on the basis of previously accepted or established statements.Definitively speaking, a theory is a unifying principle that explains a body of facts and the laws based on them. In other words, it is an explanation to a set of observations. Additionally, in contrast with a theorem the statement of the theory is generally accepted only in some tentative fashion as opposed to regarding it as having been conclusively established."Basically speaking, the major difference is that a theoryis not "conclusively established", whereas a theorem is.

Why does one replace voltage sources with a short circuit and current sources with an open circuit when using Thevenin's Theorem Long explanation please?
A: THEVENIN theorem simply is a way to simplify a complex input and resistance to a simple form. maybe you are confusing it with nodal analysis
