Geometry Adjacent Angles Geometry Adjacent Angles In geometry, adjacent angles, often shortened as adj. ∠s, are angles that have a common ray coming out of the vertex going between two other rays, with no overlap of the regions "enclosed" by the two angles. In other words, they are angles that are side by side, or adjacent. An angle can be defined as a figure which is formed by the two rays. These two rays are known as sides of the angle. The sides of the angle sharing a common endpoint which is known as the vertex point of the angle. On the vertex point the actual angle is formed by the two rays. In the mathematics, angles are usually considered in the Euclidean plane but in some of the case angles are also defined in non- Euclidean geometry. In the mathematics angles are used to determine the measurement of an angle or of a rotation. The word angle comes from the Latin word ‘angulus’ which mean refers to ‘a corner’. In the mathematical term, an angle with the measurement can be represented by the symbol (‘∠‘). In the concept of mathematics there are various types of angles are defined that are helpful in the terms of understanding the concept of angles. Like acute angle, right angle, obtuse angle, straight angle and reflex angle. These are different types of angle that provide the deep understanding of the angle’s concept.

Here we are going to discuss about the one of the property of the angles that provide the lots of concept to solve the problem that is related to the higher grade students. Adjacent angles are the different kind of angles that helpful in solving different kind of problem. Adjacent angles are the angles that are formed by the two angles. It means that two angles are adjacent if they have a common side and they are created on a common vertex but don’t overlap to each other. on the vertex ‘A’. It means that both the given angles share a common side. We can see that they can also share a common vertex. That’s why we can say that the given angles ∠CAD and ∠BAC are adjacent to each other. In the simple mean we can say that the newly formed angle ∠BAD from ∠CAD and ∠BAC are known as the adjacent angles. In the general Adjacent Angles Definition, we can define the adjacent angle as neighboring angles. It means that the word adjacent general mean is “next”, which defines the adjacent angles are angles just next to each other. Adjacent angles share a common vertex and a common side, but do not overlap. Let’s take some examples that help in understanding the concept of adjacent angle. Example: Suppose ∠CAD and ∠BAC is adjacent angles. Now you need to find the measurement of ∠CAD, if the measurement of ∠BAC = 48o and ∠ DAB= 65o? Solution: In the above question given that ∠BAC = 48o and ∠ DAB= 65o then we can say that ∠DAB = m ∠CAD + m ∠BAC, 65o = m ∠CAD + 48o, m ∠CAD = 65o – 48o, m ∠CAD = 17o. Now we can say that the adjacent angles are neighboring angles to each other. From the above example we get the measurement of angle m ∠CAD is equal to the 17o..
