Welcome to our lesson on directed angles!A directed angle consists of two rays: an initial side and a terminal side.When we rotate counterclockwise, against the direction of clock hands, we create a positive angle.When we rotate clockwise, following the direction of clock hands, we create a negative angle.The direction of rotation determines whether an angle is positive or negative, which is crucial in many mathematical and real-world applications.A directed angle can rotate through any number of degrees, creating various angles based on the amount and direction of rotation.Now that we understand how directed angles are formed, we're ready to learn how to measure them.Let's explore how we measure directed angles using both degrees and radians.Here are some common angle measurements in both degrees and radians.
