Drawing an angle in standard position always starts the same way—draw the initial side along the positive x-axis. 1. amath \begin{center} \begin{graph} Draw an arrow representing the correct amount of rotation. And this is the origin zero or 3 60 Not we know 300 is gonna be somewhere in between 2 70 and 360. 130° ! We do that by dividing the angle measure in degrees by 360°. BIG PICTURE ! Then, we can find the Coterminal angle and find the reference angle using the chart above. For example, to draw a 90° angle, we calculate that 90° _ 360° = 1 _ 4. Two di erent angles may have terminal sides which coincide, in which case we call the angles coterminal. Here. definition: An angle is in standard position if the vertex is at the origin and the initial side is on the positive x-axis. We do that by dividing the angle measure in degrees by 360°.
