1.Vertical angles are two angles which are opposite to each other at the intersection of two lines. These angles have equal measures and will never form a linear pair.
2.Only 1st and 2nd pairs of angles are supplementary angles out of the given three. Two angles are supplementary when they add up to 180 degree. They do not have to next to each other, just so long as the total of the two angles equal to 180 degree.
The line through points A, B and C is a straight line. ∠1 and ∠2 are supplementary. If two angles form a linear pair, the angles are supplementary. A linear pair forms a straight angle which contains 180º, so you have 2 angles whose measures add to 180, which means they are supplementary
