HAPTER 1 Trigonometric Functions 360 360 4 1.1 Angles ■ Basic Terminology ■ Degree Measure ■ Standard Position ■ Coterminal Angles Line AB A B Two distinct points A and B determine a line called line AB. The portion of the line between A and B, including points A and B themselves, is line segment AB, or simply segment AB. The portion of line AB that starts at A and continues through B, and on past B, is the ray AB. Point A is the endpoint of the ray. See Figure 1. In tr...
