Parallelogram proof
WebMay 9, 2024 · The proof for the resultant vector in Parallelogram addition is as follows, Consider a parallelogram O A B C as shown in the figure, Let P & Q be two adjacent sides of parallelogram, and R be the resultant vector obtained by addition of vectors P & Q, Now, drop a perpendicular from C on O A so that they meet at A. Webstep.2. prove that λx, y = x, λy , i.e.prove λx, y − x, λy = 0, the proof is similar to proving x + y, z = x, z + y, z , you may use x + y, z = x, z + y, z and − x, y = − x, y = x, − y in your proof and the latter is easy to prove.
