In this case, the middle segment connecting two sides of a triangle is Z.
This means that
Finally we have that:
The length of the middle segment is 7 units
Proof by contadiction.
Let assume there exist such positive integers and
whose sum is a prime number
, that their greatest common divisor is greater than 1.
Since is a prime number and
, then
, but we assumed earlier that
, and there are no two positive integers that sum up to 1.
