WebFACTS to remember about Law of Sines and SSA triangles: 1. In a triangle, the sum of the measures of the interior angles is 180º. 2. No triangle can have two obtuse angles. 3. The hypotenuse is always the longest side in a right triangle. So, when working in a triangle with , sin A must be less that +1 (and greater than -1). 4. WebUse the law of sines if two angles and a side are known (ASA or AAS) or two sides and an opposite angle are known (SSA). For convenience, when labeling a triangle, the side opposite an angle is named with the same letter, but lowercase. Figure 2: Example of triangle used for law of sines. Law of Sines

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. WebSolution: Here, calculate the length of the sides, therefore, use the law of sines in the form of. a sinA = b sinB a s i n A = b s i n B.
