hi people, got a simple question here.. assuming it is simple it seems so... but has been a long time since geometry, so looking for help :) assuming only the length of a diagonal of a rectangle is known (say 20"), is it possible to find the length & breadth..? stating to be a rectangle, as there is no clarity if this is a square or not... any help will be appreciated!
does the diagonal length of a piece of paper determine the exact size of the paper? are two right triangles congruent if they have the same diagonal? I.e. does one side and one angle determine a triangle? do you know pythagoras theorem?
