Answer:
1: false
2: true
3: true
Explanation:
1: Supplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees. therefore its not true
2: Whenever there are two adjacent angles which are supplementary, they form a linear pair. Therefore, the answer is Linear Pair.3: The complement of
an acute angle A is the angle 90° – A. For example, the complement of 20° is 70°. so the complement of 90° is 10°
