Answer:
(e) alternate interior angles
Explanation:
You want a description of angles 3 and 5 in the diagram of a transversal crossing parallel lines.
Where are they?
Angles 3 and 5 are on opposite sides of transversal 'c'. Hence, they are described as "alternate."
Angles 3 and 5 are between the parallel lines 'a' and 'b'. Hence, they are described as "interior."
These descriptors are combined, so that we call angles 3 and 5 "alternate interior angles."
