Real Number Line

Unfortunately, we don’t have a template for real numbers as is the case for rational numbers.

Real Numbers are the union of Rational Numbers and Irrational Numbers.

We can’t write down a complete number for an irrational number like the square root of two.

However, we argue it exists because a right triangle with sides of length 1 has a hypotenuse with a length of the square root of two.

Any integer qualifies as being a rationak number.
