Question 567032: how can you write an indirect proof that two obtuse angles cannot form a linear pair?

Assume that they do form a linear pair. Since both angles' measures are greater than 90 deg, then their sum must be greater than 180 deg. However, angles form a linear pair if and only if their sum is 180 deg, so contradiction.
