Answer:
B) A linear pairs consists of supplementary angles
Step-by-step explanation:
First let's see the definition of linear pair.
The two adjacent angles add up to 180° (supplementary) is called linear pair.
Example:
If ∠A and ∠B said to be linear pair, then they must be adjacent angles and add up to 180 degrees.
∠A + ∠B = 180°
From the definition, we can find the answer.
A) in correct because complementary angles add up to 90 degrees.
B) Correct (A linear pair consists of supplementary angles)
C) In correct because the pair consists of adjacent angles
D) In correct because vertical angles is nothing but 90°
