1. Alternate Interior Angles Theorem

2. Definition of Congruence

=================================================

Explanation:

Alternate interior angles are formed when you have two parallel lines, and a transversal. They are inside the parallel lines (hence the "interior") and they are on alternate sides of the transversal. This fits the description of angles ELK and BKL. Alternate interior angles are congruent whenever we have parallel lines like this.

The definition of congruence is basically saying if two angles are congruent, then they have the same measure. This is what it means to go from the statement to the statement . The small 'm's indicate "measure of"
