if you do work with exposure triangle

How exactly one can work with exposure triangle?

I don't know, seems to ba a teaching aid to me as to understand how shutter speed aperature setting and ISO may be manipulated,

But triangle is a rigid figure, not like a parallelogram. Nothing can be manipulated in a given triangle.

Is it supposed to be a mathematical graphical construct from which you can extrapolate settings for your camera or just an illustrative picture to get over some concepts?, I honestly don't know it seems to me the latter, and frankly you are loosing me on this, I am not an advocate of it.

The "triangle" is an exclusively graphical construct - unrelated to the simple math relating to the independent variables corresponding to camera settings that users are able to adjust values of.

Where the simple mathematical inter-relationships are "apples", graphical shapes are "oranges" ...

In browsing through many Google image-search results for the search terms "exposure triangle", I found these examples of valiant attempts to "allude to" the inter-relationships. Nevertheless, none of these graphical creations (displayed below) succeed in actually being meaningfully functionally useful for purpose of the actual making of mathematical calculations:
