FORCE VECTORS VECTOR OPERATIONS & ADDITION COPLANAR FORCES. The law of cosines generalizes the pythagorean theorem, which holds only for right triangles: if the angle γ is a right angle (of measure 90 degrees, or π / 2 radians), then cos γ = 0, and thus the law of cosines reduces to the pythagorean theorem:, because the addition law for vectors allows several options for equivalent vectors. you might reach the correct answers by a different routes to those used in these solutions. a. ac ab= =2b b. be ad= (parallel and equal in length) = d. c. hg bc= = (parallel and equal in length) = ab b(is midpoint of ac ) = b. d. df ac = = (parallel and equal in length) = 2. b. e. ae ad de = +.
