Fallacies in mathematics

Mathematicians can be wrong at times and and sometimes this errors lead to interesting results.And sometimes is some intentional effort to find foolproof solutions and really some outstanding proofs that really amaze people by unbelievable conclusions and try to show that mathematics is pointless(no,,actually not coz every fallacy is based upon some error which only a good mathematican can notice).This is what is meant by fallacies

So under this discussion u can share some of fallacies u know or mayb u hav derived urself........ Some of the fallacies i know of till date are:-

  1. The fallacy of the isosceles triangle.

  2. The fallacy of the right angle.

  3. The fallacy that 4 = o.

  4. The fallacy that +1 = -1.

  5. The fallacy that all lengths are equal.

  6. The fallacy that the sum of the Squares on two sides of a triangle is never less than the square on the third.

7.The fallacy that every 2 consecutive numbers are equal

8.The fallacy of the radius of a circle is indeterminate

  1. The fallacy that the four points of intersection of two conics are collinear.

and many more....list is endless...in every branch of mathematics really learning some mathematical fallacies is fun....u can share some

All fallacies seem to be of immense astonishment filled with humor, but it is often shown to be violating some or the other basic mathematical rules, axioms, postulates and principles. Shourya Pandey · 4 years, 2 months ago
