Answer 3

both <1 and 76 are on the "inside" of the two parallel lines
another word for inside is *interior*

they are on opposite sides of the crossing line. another way to say that is
they are *alternate* angles

they are *alternate interior angles formed by a transversal across two parallel lines*
