when two lines intersect,do they always form a linear pair?
Yes, its true. There will be 4 such linear pairs formed when two lines intersect.
Statement 1: When two lines intersect each other, only the angles forming linear pair are supplementary.
Statement 2: When two lines intersect each other, angles forming linear pair are supplementary.
