We know that anything congruent is equal. Unequal things exhibit a property called inequalities.

Example:

Let us look at some examples of inequalities.

**1.**Two unequal lines

**2.**Two unequal angles

**3.**Two unequal boxes

In this chapter, we will deal only with inequalities in triangles.

Let us look at a few theorems on inequalities in triangles.

Theorem 6

If two sides of a triangle are unequal, the angle opposite to the longer side is larger (or greater).

Theorem 7

In any triangle, the side opposite to the larger (greater) angle is longer.

Theorem 8

The sum of any two sides of a triangle is greater than the third side.
