Johann Heinrich Lambert is credited with the first proof that pi is irrational in 1768.
Johann Heinrich Lambert
In the 18th century, Johann Heinrich Lambert was the first to prove that pi is an irrational number. However, his proof requires some pretty heavy-duty mathematics. In the 19th century Charles Hermite found a proof which is simpler but still requires requires knowledge of fairly advanced calculus.

It is not possible to prove something that is not true. The square of 2 is rational, not irrational.
Root signs didn't show up

This is impossible to prove, as the square root of 2 is irrational.

The square root of 2 is 1.141..... is an irrational number
Because 3 is a prime number and as such its square root is irrational
