www.mathcounts.orgUsing the properties of the angles created by parallel lines cut by a transversal, we see that the angle labeled 4 and the angle labeled 6 are alternate interior angles, and alternate interior angles are equal. So, if the angle labeled 4 measures 104, it follows that the angle labeled 6 also measures 104 degrees. Next, we notice that the
