Answer 1

5) a) complementary

6) b) supplementary

7) c) vertical angles

Explanation:

5)

The sum of the complementary angles = 90 degrees

According to the graph, both angles add up to 90 degrees

Answer: a) complementary

6)

Straight angle is equal 180 degrees

The sum of the supplementary angles = 180 degrees

Answer 2

5. a) complementary; 6. b) supplementary; 7. c) vertical angles

Explanation:

Question 5

The sum of the two angles is 90°.

The angles are complementary.

Question 6

x° + 62° = 180°

The angles are supplementary angles.

Question 7

The angles are opposite each other where the two lines cross.

∴ They are vertical angles.

Note: "Vertical" in this context doesn't mean "up-and-down." It means the angles share the same vertex (corner point).
