Answer:
< 1 and < 3 are Corresponding Angles.
Step-by-step explanation:
Given the two parallel lines, L1 and L2, and the transveral across those two lines:
Then < 1 and < 3 are corresponding angles, since they are both on the same side of the transversal and in the same relative position. Corresponding angles are congruent, so < 1 and < 3 measure the same number of degrees.
