Ruler-and-compass construction
(Redirected from Trisection of an angle A number of ancient problems in plane geometry involve the construction of lengths or angles using only an idealized ruler and compass , or more properly a straightedge and compass The most famous ruler-and-compass problems have been proven impossible, in several cases by the results of Galois theory . In spite of these impossibility proofs, some mathematical novices persist in trying to solve these problems. Many of them fail to understand that many of these problems are trivially solvable provided that other geometric transformations are allowed: for example, squaring the circle is possible using geometric constructions, but not possible using ruler and compass alone. Mathematician Underwood Dudley has made a sideline of collecting false ruler-and-compass proofs, as well as other work by mathematical cranks , and has collected them into several books.

Wulf 17th April 2007 - 11:11 PM Taken from en.wikipedia.org/wiki/Proof_that_0.999..._equals_1
QUOTE Skepticism in education
Students of mathematics often reject the equality of 0.999 and 1, for reasons ranging from their disparate appearance to deep misgivings over the limit concept and disagreements over the nature of infinitesimals. There are many common contributing factors to the confusion:
Students are often "mentally committed to the notion that a number can be represented in one and only one way by a decimal." Seeing two manifestly different decimals representing the same number appears to be a paradox, which is amplified by the appearance of the seemingly well-understood number 1.[12]
Some students interpret "0.999" (or similar notation) as a large but finite string of 9s, possibly with a variable, unspecified length. If they accept an infinite string of nines, they may still expect a last 9 "at infinity".[13]
Intuition and ambiguous teaching lead students to think of the limit of a sequence as a kind of infinite process rather than a fixed value, since a sequence need not reach its limit. Where students accept the difference between a sequence of numbers and its limit, they might read "0.999" as meaning the sequence rather than its limit.[14]
