Question

consider the figure below. what is the main difference between linear pairs and supplementary angles? supplementary pairs must have different measures for each individual angle. linear pairs must be vertical. linear pairs must be adjacent. supplementary pairs must have congruent angles.

Explanation:

Linear - pair angles are adjacent and supplementary (sum to 180°). Supplementary angles just sum to 180° and don't have to be adjacent. So the key difference is that linear pairs must be adjacent.

Answer:

C. Linear pairs must be adjacent.
