Hi! Say, what exactly is the plural of "rhombus?"  We aren't sure if it 
is "rhombi" or "rhombuses."  Sure hope you can help!

Hey David,Brian,Luke, and Beth,

I must say I was never very good at this stuff but I looked it up and 
according to my dictionary it is both. I looked in the "American Heritage
Dictionary" and they list both as possible plural forms. I prefer rhombuses,
but that is just my personal preference.
