WebImportant Facts About SSA Triangles and the Law of Sines. Here are some important facts about SSA triangles and the Law of Sines: The sine of an angle must be greater than − 1 and smaller than + 1. For example, if θ is the angle, then − 1 < sin. ⁡. θ < 1. A triangle can never have two obtuse angles. WebTo solve an SAS triangle use The Law of Cosines to calculate the unknown side, then use The Law of Sines to find the smaller of the other two angles, and then use the three angles add to 180° to find the last angle.
