WebJan 31, 2024 · To calculate the area of an equilateral triangle, you only need to know the side: area = a² × √3 / 4. Since √3 / 4 is approximately 0.433, we can formulate a quick … WebMay 26, 2024 · The four cases are: Case 1: One side and two angles. Case 2: Two sides and one opposite angle. Case 3: Two sides and the angle between them. Case 4: Three sides. Note that if we were given all three angles we could not determine the sides uniquely; by similarity an infinite number of triangles have the same angles.

WebNov 19, 2024 · With just the definitions of sine, cosine, and tangent, you can solve any right triangle. If you’ve got the Law of Sines and the Law of Cosines under your belt, you can solve any triangle that exists. (Some sets of givens lead to an impossible situation, like a “triangle” with sides 3-4-9.) Really, it’s pretty straightforward. WebMar 26, 2016 · Solve for the missing side. You divide by sin 68 degrees, so. Repeat Steps 3 and 4 to solve for the other missing side. Setting b and c equal to each other, you have this equation: Cross multiply: Divide by sin 68 degrees to isolate the variable and solve: State all the parts of the triangle as your final answer. WebSolving SSS Triangles. "SSS" means "Side, Side, Side". " SSS " is when we know three sides of the triangle, and want to find the missing angles. To solve an SSS triangle: use The Law of Cosines first to calculate one of the angles. then use The Law of Cosines again to find … Look at the triangle and decide whether you need to find another angle using 180°… It works for any triangle: a, b and c are sides. A, B and C are angles.
