What is an angle

The video tutorial explains the concept of angles, focusing on the definition and properties of angles formed by two non-collinear rays with a common endpoint, known as the vertex. It covers how to label angles correctly, emphasizing the importance of the vertex's position in the label. The tutorial also discusses measuring angles in degrees using a protractor, highlighting the significance of the measure of an angle in geometry.
