Definitions
Before we dive into the examples, let’s first define some key terms that will be useful for understanding adjacent angles.
- Angle: An angle is a measure of the amount of turn between two rays with a common endpoint. It is usually represented by the symbol “?” and is measured in degrees.
- Vertex: The vertex of an angle is the common endpoint of the two rays that define the angle.
- Ray: A ray is a straight line that has one endpoint and extends indefinitely in one direction.
- Side: The sides of an angle are the two rays that define the angle.
Now that we have defined these terms, let’s move on to an example of an Adjacent Angle:
