Learn how to determine the angle of elevation and angle of depression

The video tutorial explains the concepts of angles of elevation and depression, which are defined in relation to a horizontal line. Angles above the horizontal are called angles of elevation, while those below are angles of depression. The teacher uses a figure to demonstrate these concepts, identifying horizontal lines and corresponding angles. The tutorial concludes with guidance on homework questions, emphasizing the identification and naming of angles.
