Question 554341
<pre>
It's like the red square and the green square below.  Squares ARE
parallelograms, by the way.  So the answer is ---- (you count 'em):

{{{drawing(400,400,-3,3,-3,3,

red(line(-2,2,2,2),line(2,2,2,-2),line(2,-2,-2,-2),line(-2,-2,-2,2)),

green(line(-3,0,0,3),line(0,3,3,0),line(3,0,0,-3),line(0,-3,-3,0))
 
)}}}
