WebSep 15, 2024 · Solution: Let a and b be the lengths of the sides, and let the diagonals opposite the angles C and D have lengths c and d, respectively, as in Figure 2.2.2. Then we need to show that. c2 + d2 = a2 + b2 + a2 + b2 = 2(a2 + b2) . By the Law of Cosines, we know that. c2 = a2 + b2 − 2ab cos C , and d2 = a2 + b2 − 2ab cos D . WebSolving SSA Triangles. "SSA" means "Side, Side, Angle". " SSA " is when we know two sides and an angle that is not the angle between the sides. To solve an SSA triangle. use The Law of Sines first to calculate one of the other two angles; then use the three angles add to 180° to find the other angle; finally use The Law of Sines again to find ...
