# SAS Inequality

A relatively simple principle called SAS inequality lets us solve triangles without actually doing any complicated math. Let''s see how it works:

## What is SAS inequality?

SAS stands for "side-angle-side." Here''s how SAS inequality works:

If one triangle has two sides that are congruent to the two sides of a second triangle*And:*

If the first triangle has an angle that is greater than the angle of the second triangle*Then:*

We know that the third side of the first triangle must be longer than the third side of the second triangle.

Here''s what that looks like:

Based on the above triangles, the equation for SAS inequality is simple:

If

*and*if

*and*

*then*

Okay, so it''s not

*that*simple of an equation. But it''s still very handy for solving triangles.
