Question

3 multiple answer 1 point 1 2 adjacent vertical complementary supplementary linear pair

Explanation:

Step1: Define adjacent angles

Adjacent angles share a common side and a common vertex. Angles 1 and 2 share a common side and a common vertex, so they are adjacent.

Step2: Define vertical angles

Vertical angles are opposite each other when two lines intersect. Angles 1 and 2 are not opposite, so they are not vertical.

Step3: Define complementary angles

Complementary angles add up to 90 degrees. There is no indication that ∠1 + ∠2=90°, so they are not complementary.

Step4: Define supplementary angles

Supplementary angles add up to 180 degrees. Since angles 1 and 2 form a straight - line, ∠1+∠2 = 180°, so they are supplementary.

Step5: Define linear pair

A linear pair is a pair of adjacent angles whose non - common sides are opposite rays. Angles 1 and 2 are adjacent and their non - common sides are opposite rays, so they are a linear pair.

Answer:

adjacent, supplementary, linear pair
