35 PLANE TRIGONOMETRY 36 In general we call a line segment positive if it generated by a point moving from left to right, as AB Figure 15. We indicate such a line segment by AB. distances. is in Figure 16. the line segment is generated by a point moving from right to left, we call the line segment negative, and indicate If it by BA. ) Thus, to B, in Figure 15, BA = -AB. But it is desirable often to distinguish between positive and negative distances when the direction is neither from left to right nor from right to left.

In Chapter III we considered the solution of the right triangle. In this chapter we shall be concerned with the solution of the oblique triangle, for which we use two important laws giving relations between the sides and the angles of such a triangle. We proceed to the derivation of the first of these laws, called the law of sines: Law of Sines. The sides of a triangle are proportional to the sines of the angles opposite.
