WebSolving Triangles Trigonometry is also useful for general triangles, not just right-angled ones . It helps us in Solving Triangles. "Solving" means finding missing sides and angles. Example: Find the Missing Angle "C" Angle C can be found using angles of a triangle add to 180°: So C = 180° − 76° − 34° = 70° We can also find missing side lengths. WebDec 12, 2024 · How to: Given a trigonometric identity, verify that it is true. Work on one side of the equation. Do NOT - absolutely NOT EVER - use Properties of Equality like adding/subtracting/multiplying/or dividing the same expression to both sides of the equal sign. Work ONLY on one side of the equal sign.
