Ordering : The proof that the square root of 2 is irrational
You have to create a proof that the square root of 2 is irrational.


You will see that it begins by assuming that the square root of 2 is rational, in other words that the square root of 2 can be expressed as a fraction. That fraction is assumed to be in fully simplified form, in other words the numerator a and denominator b have no common factors.



Use your mouse to drag statements into the correct order. The gauge shows if you are moving in the right direction.


Once you have correctly ordered the statements you will have created a mathematical proof.
