Is this alternate interior or alternate exterior? Pls help will mark brainliest

Alternate interior

Step-by-step explanation:

The first thing you need to identify is if 1 and 2 are exterior or interior angles. They are in the interior and I remember this by examining the two horrizontal lines. there is space above the horizontal lines, inbetween, and below. The section below and above are exterior/on the outside. The section inside the two horizontal lines is interior. That eliminates Alternate exterior automatically but if you wanted to take it to the next step, an alternate interior angle always consistes of the alternate side of the transversal line. Thats the line running through the horizontal/parrel lines. They also have to be adjacent.
