Respuesta :

Given: lines l and m are parallel, and line t is a transversal.

angle pair result/justification

1 and 2 are equal (vertical angles)

6 and 8 are equal (corresponding angles)

1 and 4 are equal (alternate exterior angles)

4 and 8 are supplementary angles (i.e. add up to 180 degrees, a straight angle)

Note:

alternate angles are on opposite sides of the transversal, and each attached to a different (parallel) line.

If they are both enclosed by the parallel lines, they are alternate interior angles (examples: angles 2 and 3, 6 and 7)

If they are both outside of the two parallel lines, they are alternate exterior angles (examples: angles 1 and 4, 5 and 8)

Answer:

<1 & <4

Step-by-step explanation:

The only alternate exterior angle pair would be 1 & 4, for the reason that <1 & <2 are vertical, <6 & <8 are corresponding, and <4 & <8 are adjacent.  Therefore, that being said, the only alternate exterior pair would be <1 and <4. Hope this helps!
