<VV> Muffler Heat Shields

[William Pierson]

To be honest, I had never heard the word and didn't take the time to ask my retired English teacher wife the meaning. I think tho, that I have the years backwards. Someone else needs to clarify.

American high school geometry text (the Texas version) usually define a 
trapezoid as a quadrilateral with exactly two sides parallel.  A 
trapezium is usually defines as a totally irregular quadrilateral.  
Common usage often deviated from this practice, considering these terms 
as interchangeable.
