# Linear Pair Conjecture

### Explanation:

A **linear pair of angles** is formed when two lines intersect. Two angles are said to be **linear** if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

### The precise statement of the conjecture is:

**Conjecture (***Linear Pairs Conjecture* ):
Linear pairs of angles add up to 180 degrees.
