What Is Parallax? : ScienceAlert

Mathematically speaking, the relationship between any two observation points and a distant object can be summed up in what's known as a parallax angle .

So long as some of the information is known – such as an angle between the lines of sight and the distance between observations – trigonometry can be used to deduce how far away the object is.
