<1 and <2 are a linear pair. true or false
False. A linear pair consists of two adjacent angles whose sum is 180 degrees. Therefore, if <1 and <2 are a linear pair, their measures must add up to 180 degrees.
False.
A linear pair of angles is formed when two adjacent angles are supplementary, meaning they add up to 180 degrees. The symbol "<" indicates an angle measurement, not an angle itself.
Therefore, the statement <1 and <2 are a linear pair cannot be determined based on the given information.
