The statements that you offer as examples of false proofs are actually not false proofs, they are merely false assertions. You have not offered any line of reasoning. You would have to explain why 1 equals two, or all triangles are isosceles, in order to have a false proof. Here is a recent example of a false proof. Last month, in April 2013, the continent of North America experienced colder weather than the average for April. As a result, some people have concluded that global warming is not happening. The belief is that if there is some part of the world that was not warmer than average last month, then the world must not be on a long-term warming trend. This is, of course, not true. The long-term climate trends show global warming, but there are occasional fluctuations.
"Proofs are fun! We love proofs!"
Aww, man. Proofs? You're on your own.
CPCTC represents Corresponding Parts of Congruent Triangles are Congruent. You would use this in Triangle Proofs.
It does not. Such "proofs" depend on some mathematical or logical fallacy that is not easy for an amateur to spot.
The possessive form of the plural noun proofs is proofs'.Example: I'm waiting for the proofs' delivery from the printer.
Study the proofs of each chapter in your book, also the solved examples related to them. Read the definitions carefully. Practice systematically.
Proofs from THE BOOK was created in 1998.
1 does not equal 2. There are many supposed proofs that work on the assumption that readers will not notice an attempt to divide both sides by zero.
