Dear The Mathematical Association Of America,
I am currently in a bit of a predicament. I recently bought a shelf from my local Ikea store, and on the instructions there is a shape that has caused severe disagreement. It's sides are of measurements (starting from top side, going clockwise) Sin-1(0.232344345), tan-1(0.9494938), Sin-1(0.232344345) and Cos-1(0.5643420894) With corners at 90(degrees), the colour of the shape in question is bright turquoise, and if you put two of these shapes together they will make a strong, capable shelf bracket.
The problem is that I feel this shape is most certainly a rhombus, while my friend Toby Jenkins insists it's a trapezoid. Is there any way you can provide an answer/solution to this charade?
Thanking you in advance
A Richards.
