A strict inequality is an inequality where the inequality symbol is either > (greater than) or < (less than). That is, a strict inequality is an inequality which has no equality conditions.

An example of a well-known strict inequality is the Triangle Inequality, which states that, in a nondegenerate triangle ABC, the following relation holds:

AB+BC>AC

A non-example is the Trivial Inequality which states that if x is a real number then \displaystyle x^2 \geq 0. This inequality is not strict because it has an equality case: when x = 0, x^2 = 0.
