If you drag the ORANGE dots you can produce different rhombuses. Devise a [br]measure of 'Squareness' that allows you to arrange any collection of [br]rhombuses in order of 'Squareness'.[br][br]How many such measures can you devise?[br]Which of these measures do you prefer? Under what circumstances?[br][br]Under what circumstances does the average of two different measures of squareness lie between the two individual measures of squareness?
