Answer 1

Complementary angles : Angles whose sum is 90° are known as complementary angles.

• True, 20° and 70° are complementary angles because their sum is 90°
• True, 88° and 12° are also complementary because their sum is 90°

Supplementary angles : Angles whose sum is 180° are called supplementary angles.

• False, 80° and 180° are not supplementary because their sum is not 180°
• True, 0° and 180° are supplementary because their sum is 180°

⭕Your Answer⭕

1) True

Because 20° +70° = 90°

Hence , this is true.

2) False

Because 88° + 12° = 100°

Hence , this is false.

3) False

Because 80° + 180° = 260°

Hence, This is false

4) True

Because 0° + 180° = 180°

Hence, this is true
