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