Web1. Take for example the obtuse triangle. Beginning with the angle in blue (the obtuse one) and counterclockwise, call the vertices A, B, C, and call D where the straight angle is. If we call α the blue angle, we then have by Pythagoras. A C 2 = C D 2 + A D 2. And on the triangle Δ C D B, again by Pythagoras: B C 2 = B D 2 + C D 2 B C 2 = B D ... WebUse the Law of Sines to find a triangle with one obtuse angle if A = 50 degrees, a = 23, and b = 26.
