WebFor each angle drawn in standard position, there is a related angle known as a Reference Angle. Reference angle is the smallest angle formed by the terminal side and the x-axis (the horizontal axis). The reference angle is positive and has a value anywhere from 0° to 90° (Acute angle). Reference angle can be in any of the four quadrants. infant baby hair accessories
