What kind of quadrilateral is the
shape shown here? a) Square only, b) rhombus and square, c) rectangle and square, d)
parallelogram and square, or e) parallelogram, rectangle, rhombus, and square.

Let’s see what we know about this
figure. We notice that it has two sets of
parallel sides. And that makes it a
parallelogram. And we’ll just go ahead and
eliminate all the options that don’t include parallelogram because this is a
parallelogram. It has two sets of parallel
sides.

We notice that all the sides are
equal. And that makes it a rhombus because
all four sides are equal. And all four angles are right
angles. It’s also a square. And every square is a
rectangle.

That means this shape is a
parallelogram, rectangle, rhombus, and square. And though we would usually call a
shape like this a square, all four of these descriptions are accurate.
