Question

parallel lines and transversals

1. looking at the image:

if you have two // lines cut by a transversal, then the alternate exterid angles are...
congruent
supplementary
+180°
all of the above
none of the above

Explanation:

When two parallel lines are cut by a transversal, alternate exterior angles are congruent. Supplementary angles add up to \(180^{\circ}\), but alternate exterior angles are not supplementary in general. Since alternate exterior angles are congruent, the options "Supplementary \(+ 180^{\circ}\)", "All of the above" and "None of the above" are incorrect.

Answer:

Congruent
