Question

1. looking at the image: if you have two // lines cut by a transversal, then the vertical angles are... congruent ≅ supplementary + 180° all of the above none of the above

Explanation:

Vertical angles are formed when two lines intersect. By the vertical - angles theorem, vertical angles are congruent (have equal measures). Supplementary angles add up to \(180^{\circ}\). Vertical angles are not supplementary to each other (they are congruent). Since vertical angles are only congruent and not supplementary, the option "All of the above" is incorrect, and "None of the above" is also incorrect.

Answer:

Congruent
