In geometry, angles are classified based on their measure. Understanding how to name angles is essential for solving geometry problems and accurately communicating the position of angles. This worksheet on naming angles in geometry will help students practice identifying and naming different types of angles.
Angles are formed when two rays meet at a common endpoint, called a vertex. The measure of an angle is determined by the amount of rotation from one ray to the other. By naming angles correctly, we can clearly describe their positions and relationships in geometric figures.
