Quadrilateral RSTU, shown at right, has
integer coordinates.
Which of the following arguments
correctly answers and justifies the
question: "Is quadrilateral RSTU a
regular quadrilateral?"
A. Yes, it is a regular quadrilateral
because all sides are the same length.
B. Yes, it is a regular quadrilateral
because the diagonals are
perpendicular.
C. No, it is not a regular quadrilateral
because RSTU is not a parallelogram.
D. No, it is not a regular quadrilateral
because the diagonals are not the
same length.

Quadrilateral QRST and quadrilateral
WXYZ, shown at right, both have integer
coordinates.
Are quadrilateral QRST and
quadrilateral WXYZ similar
quadrilaterals?
A. Yes, both are rectangles.
B. No, although the corresponding
angles are congruent, the rectangles
are not the same size.
C. Yes, corresponding angles are
congruent and corresponding sides
have the same scale factor.
D. No, although the corresponding
angles are congruent, quadrilateral
WXYZ is not a reflection of
quadrilateral QRST.
