Pythagoras method to complete einstein special relativity issues

A simple alternative to solve problems in the material of Einstein's special relativity. Einstein's special material of relativity is material that has so many similarities. Equations in the material of Einstein's special relativity among others are time dilation equations, long contractions, relativistic masses, and relativistic energy. This research will discuss how the relationship between the Pythagorean theorem equation and Einstein's special relativity equationand show how to use the Pythagoras method to solve Einstein's special relativity problem. Steps in this research are calculated the equation for the Pythagoras theorem, calculate the equation of Einstein's special relativity, then analyze how the relationships between the Pythagorastheorem equation with the Einstein's special relativity equation.
