WebIn trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of a triangle (any shape) to the sines of its angles. 46 relations. ... one of the founders of non-Euclidean geometry — a geometry that differs from Euclidean geometry in its definition of parallel lines. 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).
