# Reflex Angle

**Reflex angles** occur along with acute, right and obtuse angles, in the exterior of these angles. As the angle formed in the exterior of a straight angle is also a straight angle, reflex angle is not identified in a Straight angle.**Reflex angles** determine the major arc in circles. It can also be viewed as the angle measured with the opposite orientation between two rays with a common end point. If an angle is denoted by ∠A, then the reflex angle is denoted by Reflex ∠A. The sum of an angle and its reflex measure is 360º.
