Select each quadrilateral that has exactly four right angles. A) trapezoid b) isosceles c) c) trap parallelogram d) rhombus e) rectangle f) square?

An answer is given for the other version of this question. (e) rectangle, and (f) square are the correct choices.
_____
(c) parallelogram, and (d) rhombus may have exactly four right angles, but does not necessarily. A trapezoid may have two right angles, but some authors will say a figure with four right angles (or that is a parallelogram) is not any sort of trapezoid (a) or (b).
