Work Step by Step
$450^o$ is coterminal with: $450^0-360^0=90^o$ 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 $450^o$ angle in standard position, draw its coterminal angle $90^o$. From the initial side on the positive x-axis, move 90 degrees counter clockwise.
