Question

what is a logical conclusion that can be made from the drawing? <1 and <4 are vertical angles <1 and <2 are supplementary <1 and <2 are complementary <2 and <3 are vertical angles

Explanation:

Vertical angles are opposite each other when two lines intersect. Supplementary angles add up to 180 degrees and are adjacent. Complementary angles add up to 90 degrees. In the given figure, ∠1 and ∠2 are adjacent and form a straight - line. A straight - line angle is 180 degrees. So, ∠1 and ∠2 are supplementary.

Answer:

∠1 and ∠2 are supplementary
