Think about two vectors: (a1, b1, c1, ...) and (a2, b2, c2, ....)

What are the magnitudes of the sum and difference of these two vectors? Set these two equations equal to each other and simplify.

What is the scalar (dot) product of the two vectors? How is this related to the result from the first part?

@H.D. M A K , I split off your other question, and moved it to https://www.physicsforums.com/threads/when-magnitude-of-addition-is-equals-to.795617/.
