Section 5.1 Angles and their Measures Objective: Students will be able to find degree and radian measures, determine co-terminal angles, compute arc length of a sector of a circle, and compute the area of a sector of a circle. I. Find Degree Measure An angle is formed by rotating a ray about its endpoint. Initial side of the angle is the starting position of the ray. Terminal side of the angle is the final position of the ray. Vertex of the angle is the common endpoint, often named by a capital letter such as 𝐴 . An angle is in standard position if its vertex is at the origin in the ?? -plane, and its initial side is the positive ? -axis. The measure of an angle quantifies the direction and amount of rotation from the initial side to the terminal side. The measure of an angle is positive if the rotation is counterclockwise. The measure of an angle is negative if the rotation is clockwise. A degree is one way to measure an angle. One full rotation of a ray about its endpoint is 360 degrees, denoted 360° . Therefore,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
