Geometry lesson

Well what is it ?

It is a quadrilateral but ...

Is it a trapezium or is it just a trapezoid ?

Hard to tell without getting down there with a tape measure or a theodolite but it may have two parallel sizes - with GPS driven harvesters it probably has, so that's a trapezium in that field.

Unless of course you are reading this in the USA then it would be a trapezoid. If it doesn't have parallel sides then it would be a trapezium unless you are in the UK and it would then be a trapezoid.

Another day gone and another photograph. I took quite a few today but none with as good geometry as this one.
