Interested to know what one can deduce knowing that the dot product of , with them being purely arbitrary vectors that aren't equal to one another. What does this mean?

cant really deduce anything other than that the dot products are equal to each other (obvious lol)
-also : the vectors arent necessarily parallel , as some people think !?

Roughly speaking, the 'overlap' of a and b is equal to that of c and d. But otherwise it is much like a+b=c+d, not very informative about the terms.

Yeah that's the intuitive idea I had, but i can't see what we could say about it without more information.
