1. The problem statement, all variables and given/known data
I am going the do some alignment of a shaft.I use a dial indicator for measurement, and use rim-face techniques. Then I need do calculate the total TIR (Total Indicated Runout).

Here is my result of my measurement (Dial indicator).

Top: 0
Right: +0,08
Bottom: -0,27
Left: -0,35


2. Relevant equations
Then I was being told if I want to calculate the total TIR then I have to use Pythagoras theorem.
Why do I need to use that?
What has Pythagoras theorem to do with this?
Is it posible to draw it to get better understanding?
