Your remark is just exactly what I was thinking about this essay. Also the grading I have been doing has pointed out where students did not separate the parts which apply to all problems of a kind from the parts which apply to just this particular problem.
Off topic but, I have to know… since it is am here, will my post be first or second??? I think that WordPress orders response in time by Coordinated Universal Time, which does produce some odd divisions in breaking statistics out by day though it could be worse than what I get in the Eastern Time Zone , but is at least reasonably unambiguous about ordering.
I wonder if there are other default comment orderings available. Someday I must find out how this works. Ahh yes. The bases of the triangles are the bases of the trapezoid, and their common perpendicular height is that of the trapezoid. Alternately, the typical trapezoid not a parallelogram is the difference of two similar triangles, whose bases are the bases of the trapezoid. The question about diagrams is very important. An algebraic topologist spoke of turning bad pictures into good proofs.
The two-triangle method works out a lot more easily. I think the working out all the kinds of diagrams has been the most fun of this, despite some frustrations with Photoshop in drawing them.

Asked 9 years, 3 months ago. Active 7 years, 4 months ago. Viewed times. Confusing yet? We've got the following suffixes describing shapes: -lateral, -gram, -zoid.
And still "rhombus" fits in nowhere in this crazy, convoluted scheme! To bring this all back to mathematics, and to ask my original question: Individually, I can find the etymology of each of these terms. Emily Emily Corrections were made to the nomenclature standards for order of operations, arithmetic, and other elementary tools.
Why not shapes? Show 5 more comments. Active Oldest Votes. The commonest words tend to be the most resistant to change. Since most irregularities can be explained historically, these verbs are only irregular when viewed synchronically, not when seen in their historical context. Add a comment. Part of learning higher mathematics is the periodic unlearning of things -- or rather, the re-learning of things once taken for granted.
This problem is perhaps an extension of that. However, this impediment won't severely affect those with the academic prowess to retrospectively re-learn things once taught. I still think this hinders the development of those who might have potential otherwise. But, as you said, this is not the biggest problem that math education faces; it is more like a symptom.
My theories on the downvote, in increasing order of probability: they think the US school system is perfect; they are a primary text author; they refuse to let rectangles be trapezoids; they are my angry petulant m. SE downvote stalker who enjoys doing such things. Shame on them. Every subject has things which need new names. The reason for the name less is as follows: An earlier command, more , would display a file on the terminal and pause after every page to ask more?
But it provided no way to go backwards in the file to view the previous pages. The less command appeared later, and was so named because it was like more but would also go backwards. For people already familiar with more , the name was easy to remember.
