Definition

A reflex angle is an angle that measures more than 180 degrees but less than 360 degrees.

Description

Reflex angles are often encountered in the study of rotations and circular motion, where they are used to describe angles that extend beyond a straight line. They are important in fields such as physics and engineering, where understanding rotations and angular measurements is crucial. In mathematics education, reflex angles help students develop a comprehensive understanding of angle measurement and classification, contributing to their overall geometric reasoning and problem-solving abilities.
