The Relation de Chasles is named for Michel Chasles, the French mathematician whose name is attached to several results in geometry. In school mathematics the phrase most often refers to the vector relation, where a journey from one point to another can be broken through a middle point. Because the formula is repeated so often in French classes, the name alone has become shorthand among students. Online, short clips invoking it work as a recognisable reference, shared less for teaching the rule than for the shared memory of learning it.

A short clip naming the Relation de Chasles, the vector rule from French maths, often used as a quick classroom joke or meme reaction in study edits.
This is a brief audio clip centred on the Relation de Chasles, the well known vector identity taught in French mathematics classes where one vector is split through an intermediate point. The delivery is short and abrupt, lasting under two seconds, which makes the familiar lesson phrase land like a punchline rather than an explanation. Listeners who have sat through geometry lessons recognise it instantly, and that shared recognition is the effect. It turns a routine school formula into a quick in joke, evoking chalkboards, notebooks and the feeling of a teacher repeating a rule everyone is expected to know by heart.
