Question

1. what do you call two angles whose sum is 180 degrees?

adjacent angles
complementary angles
supplementary angles
linear pair

Explanation:

• Adjacent angles are angles that have a common side and a common vertex but their sum is not necessarily 180 degrees.
• Complementary angles are two angles whose sum is 90 degrees.
• Supplementary angles are defined as two angles whose sum is 180 degrees.
• A linear pair is a pair of adjacent angles that are supplementary, but the key difference is that a linear pair must be adjacent, while supplementary angles do not have to be adjacent. Since the question does not mention adjacency, the general term for two angles summing to 180 degrees is supplementary angles.

Answer:

Supplementary angles
