What is the reference angle of radians?

When finding reference angles, it can be helpful to keep in mind that the positive x-axis is 0° (and 360° or 0 radians (and 2π radians); the positive y-axis is 90° or 2π radians; the negative x-axis is 180° or π radians; and the negative y-axis is 270° or 3 π 2 frac{3pi}{2} 23π radians.

What is the reference angle of 36?

Since 36° is in the first quadrant, the reference angle is 36° .

What is the reference angle for 275?
