Question

5 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 do not share a common side, so they are not adjacent.

Step2: Define vertical angles

Vertical angles are opposite each other when two lines intersect. Angles 1 and 2 are opposite each other when the two lines intersect, so they are vertical.

Step3: Define complementary angles

Complementary angles add up to 90 degrees. Since the two - lines are perpendicular and the non - right angles are formed by the intersection of the two lines, angles 1 and 2 are complementary.

Step4: Define supplementary angles

Supplementary angles add up to 180 degrees. Angles 1 and 2 do not add up to 180 degrees, so they are not supplementary.

Step5: Define linear pair

A linear pair of angles are adjacent and supplementary. Since angles 1 and 2 are not adjacent, they are not a linear pair.

Answer:

vertical, complementary
