Nice. I just had to solve a problem for my youngest one which was too good to not to share:
 
So, first, we don't have a TV so my children are TV-illiterates.
 
Ok, imagine the youngest one coming to me because she could solve the following maths homework:
 

On a TV quiz the 16.000 Euro Question for a candidate was:

Every rectangle is a..
1) square
2) rhomboid
3) parallelogram
 
Explain why the candidate got a second chance.

 
 
Turned out she was confused because she didn't knew how those quiz shows work.

And so that's not a maths question.

Yeah, badly formed question. Is it a math test or something else? Explain why? Does it need a 4 paragraph essay?

Well, the answer is that *all* the answers to choose from were wrong (that's the math part) so the candidate wasn't able to pick a right answer at all and had to be given a second question. The TV-social part is probably no big deal for those pesky 98%-ish kids who know their quiz shows, but for the rest it's a bit puzzling.

You could ask about recatangles and stuff without framing it as a TV quiz show.

I've been out of grade school for a few years now, but rectangles aren't parallelograms?

Wiki

 

Traditionally, in two-dimensional geometry, a rhomboid is a parallelogram in which adjacent sides are of unequal lengths and angles are non-right angled.

A parallelogram with sides of equal length (equilateral) is a rhombus but not a rhomboid.

A parallelogram with right angled corners is a rectangle but not a rhomboid.

You have 3 apples in one hand and 2 pears in the other. Why are the bananas yellow?

Sure. But "Textaufgaben" (story problems) are supposed to be a bit entertaining. As far as I'm concerned it definitely was.

Of course. But what I remember from my time in Grundschule, this type of problems were always a bit odd. Though I think the purpose is less math and more the reading comprehension to filter a text.

 

 

And I agree the entertainment value of the generational disconnect between the writer and your child not knowing TV quiz shows. ^_^

on the other side - friend of mine told how his 8 year old daughter asked something from her grandmother.

granny - ´´...aaand what´s the magic word?´´

child - ´´....mmmmm....avada kedavra!`´

I read the hierarchy as a square being both a type of rectangle and rhombus, and both of the latter being a type of parallelogram. Which is correct if you think about it.

I simply refer to Euclid who would have answered that the rectangle is a parallelogram.  Euclid, and Archimedes both defined rhomboid as having adjacent sides of unequal length and angles that are not right-angles.  A rectangle is not a rhomboid.  A parallelogram is a quadrilateral with opposites of equal lengths and opposite angles are of equal measure.  Rectangles are parallelograms.  A square is a quadrilateral with four equal sides and four right-angles.  A rectangle is not a square.

So, by the logic that we're just going to throw out 2000 year old definitions because they are inconvenient, then we can also state that a square is not a rectangle.

Everything you say up to your last line is correct, it just has no connection to the latter. ;)

Sure it does. The original premise is that the question could not be answered because a rectangle is not a parallelogram.  My point is that if a rectangle is not a parallelogram then surely a square is not a rectangle.

As the original question was whether *every* rectangle is a .... your reasoning is a bit beside the point.

Not if it self identifies as a triangle.
