Gabriel used the following theorem: When a transversal crosses parallel lines, alternate interior
angles are congruent.
Fill in the blanks in Gabriel's solution.
. Since ZLMN and Læ are a linear pair, m/x =
. Since Zx and Zy are alternate interior angles, m/y =
Since Zy and Zz are a linear pair, mZz
=
