Question
Angles 4 and 1 are what angle pair?
- Complementary
- Supplementary
- Acute
- Vertical
Hint:
Two angles are said to be supplementary angles if they add up to 180 degrees.
The correct answer is: Supplementary
Angle 4 and 1 form a linear pair, so they are supplementary.
Hence, the correct option is (a).
Supplementary angles can either be adjacent or non-adjacent. So, there are two types of supplementary angles. Each of these types of supplementary angles is explained below.
(1) Adjacent Supplementary angle.
(2) Non - Adjacent Supplementary angle.

Name a pair of angles that are vertical.
They are always equal to each other. In other words, whenever two lines cross or intersect each other, 4 angles are formed. We can observe that two angles that are opposite to each other are equal and they are called vertical angles.
