ahh yes, thanks.
i see my mistake. i confused square (vierkant) with quadrilaterals (vierhoekig,four cornerned). so i think i have to admit i was wrong, but like my dad said it it still made perfect sense when i was 8![]()
A parallelogram is a form of trapezoid? That's... unexpected...
I'm still not here
There's an issue with British and American spellings there actually, a trapezoid (AE) is the same as a trapezium (BE), this is a shape which has 2 (opposite) parallel sides. This is the shape that a parallelogram is a more specific variety (namely it has 2 pairs of parallel sides).
On the other hand a trapezium (AE) or trapezoid (BE) is a shape with no parallel sides, obviously that shape can never be a parallelogram.
(It's really funny how far off topic this has gone.)
