Angles and Coordinate Lines -Pre-University Course (PUC) Mathematics sem-1 with solutions - Learning objectives:
To understand the plane angle and measures of an angle
To convert radians to degrees and degrees to radians
To understand the concept of arc length and the area of a sector and AND
To practice problems related to the above concepts
Plane Angle: Angles in the plane can be generated by rotating a ray about its endpoint. The starting position of the ray is called the initial ray (initial side) of the angle, the final position is called the terminal ray (terminal side) of the angle, and the point at which the initial and terminal rays meet is called the vertex of the angle.
