Let´s call the hypotenuse $c$ and calculate the distance.$c^2=4^2 2^2$ $ c^2=16 4 $ $ c^2=20 $ $ c=\sqrt ≈ 4,47 $ This format will always hold true and because of that we can form a formula called the distance formula.

A right triangle is a triangle where one of the three angles is an 90-degree angle.
A very large number of geometry problems can be solved by building right triangles and applying the Pythagorean Theorem. There are no more cases as the hypotenuse has to be greater than the leg.
This is generalized by the Pythagorean Inequality and the Law of Cosines.
Pythagoras or the disciples to him constructed the first known algebraic proof of the theorem and famous writers such as Plutarch and Ciceron acclaimed him for discovering this proof.
Therefore this beautiful connection between the sides in a right triangle has been credited to him.
This theorem has been know since antiquity and is a classic to prove; hundreds of proofs have been published and many can be demonstrated entirely visually(the book The Pythagorean Proposition alone consists of more than 370).
The Pythagorean Theorem is one of the most frequently used theorems in geometry, and is one of the many tools in a good geometer's arsenal.
The Pythagorean theorem word problems exercise appears under the 8th grade (U.
S.) Math Mission and High school geometry Math Mission.
