Supplementary angle postulate11/29/2022 ![]() Supplementary angles are not necessarily adjacent angles. Supplementary angles are two angles whose measures add up to 180°. The sum of the measures is the measure of the angle formed by the two non-common arms of adjacent angles What is different between a pair of adjacent angles and a linear pair of angles? Pair of adjacent angles Linear pair of anglesĪ linear pair of angles is a pair of adjacent angles formed when two lines intersect. G) Pair of angles ∠1 and ∠2 share the common vertex O but do not share the common arm, so these angles are not adjacent. The following diagram shows two adjacent angles 1 and 2 with the common arm $\vec$, so these angles are adjacent. Three things that need to be done to keep the angles adjacent: We can treat adjacent angles as angles that are next to each other.Īdjacent angles are a pair of angles that share a common side and vertex. The word “adjacent” means “next” or “neighboring”. Having such a variety of adjacent angles in everyday life, it is worth studying and understanding which properties these angles have and what can be done with using these properties. Two roads at the T-junction, a tram rail and a sleeper, two cross-street signs, open scissors, all these real-life objects form adjacent angles. When we ride a bike, the three adjacent spokes of the wheel form a pair of adjacent angles. When we look at an open book its covers and one of the pages form a pair of adjacent angles. When we look at a watch with an hour, minute, and second hand, we see a pair of adjacent angles. Adjacent can be many things, including angles. It can be said that apartments or fences are adjacent to each other. Some have a common wall between their apartments, some have a common fence.
