How do you know if a triangle has 2 solutions
WebGiven two sides of a triangle a, b, then, and the acute angle opposite one of them, say angle A, under what conditions will the triangle have two solutions, only one solution, or no solution? Let us first consider the case a < b. Upon applying the law of sines, we arrive at this equation: Now, since h b = sin A WebJul 19, 2011 · Make sure that there is a big enough angle between these first two sides so that you can mark it. Now we have drawn the base of unknown length, the fixed angle, and the first fixed side, adjacent to the angles--the A and first S of our ASS triangle. Tape the yarn to the board at some point above the dotted line.
