A rhombus is a rectangle when one of its angles is a right angle.
(Actually, a rectangle has 4 right angles. But you only have to prove that your
rhombus has one of them for sure, because then it turns out that it must have
four of them.)
(Also, before you get all upset because a rhombus with right angles is actually
a square, we're aware of that too. Technically, a square is a special kind of
parallelogram, rhombus and rectangle too.)
