Angle: Consider a ray. If this ray rotates about its end point O and takes the position OB, then we say the angle has been generated.Angle is considered as the figure obtained by rotating a given ray about its end point. Measure of an angle is the amount of rotation from initial side to terminal side. System Read more about Trigonometric Ratios, Domains and Range[…]
