knowledge-responsibility-control (KRC) triangle: a triangle which is a symbol of the fact that knowledge, responsibility and control act together as a whole entity. In order to handle any area of ones life, it is necessary to know something about it, take some responsibility for it and control it to the degree necessary to achieve the desired result. This triangle interacts best when used with high ARC, thus it interlocks with the ARC triangle. See alsoaffinity-reality-communication (ARC) triangle and control in this glossary.
