Work Step by Step
$540^o$ is coterminal with: $540^0-360^0=180^o$ An angle in standard position has its initial side on the positive x-axis. Angle measurement is done counterclockwise from the initial side. To draw a $540^o$ angle in standard position, draw its coterminal angle $180^o$. From the initial side on the positive x-axis, move 180 degrees counter clockwise.
