Question
Which of the following angles are co-terminal angles: 480 , -240 or 600
how can we get it which is co-terminal and what does co-terminal means?????
Joshi sir comment
Coterminal angles are angles in standard position (angles with the initial side on the positive x-axis) that have a common terminal side. For example 30°, –330° and 390° are all coterminal.
To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360° if the angle is measured in degrees or 2π if the angle is measured in radians.
480 and -240 are co terminal angles because 480-360 = 120 and -240+360 = 120
