1. The problem asks to identify an angle that is greater than 180° but less than 360°. 2. Angles are measured in degrees, and a full circle is 360°. 3. Angles between 0° and 180° are called acute (less than 90°) or obtuse (between 90° and 180°). 4. Angles greater than 180° but less than 360° are called reflex angles. 5. Therefore, any angle $\theta$ such that $$180^\circ < \theta < 360^\circ$$ is a reflex angle. 6. This means the angle opens more than a straight line but less than a full circle. Final answer: The angle is called a **reflex angle**.
