The complement of a set refers to everything that is NOT in the set. A "universe" (a set from which elements may be taken) must always be specified (perhaps implicitly). For example, if your "universe" is the real numbers, and the set you are considering is 0 <= x <= 10 (that is, all real numbers between 0 and 10, inclusive), then the complement is all real numbers that are NOT between 0 and 10 inclusive - in other words, real numbers that are either less than zero, or greater than ten.

Given a Universal set, U, and a set X, the complement of X in U consists of all elements of U that are not in X.
Note that the complement of the set X will be different in different Universal sets.

complement of a setThe complement of a set is defined and shown through numerous examples. Alternate notations for complement are presented. Set-builder notation and Venn diagrams are included. Connections are made to the real world.

They are complements when they add to 90 degrees, making a right angle. For example 60 degrees and 30 degrees, or 23 degrees and 67 degrees.
