What's the relation between chess and math?

Applications in what sense? Do you think that parallel lines, octogons, permutations, and combinations are mentioned very often in chess books? Much math knowledge required to learn about triangulation?

In simple way of applying math concepts to the game of chess. That's all. 

Using three moves in a shape of a triangle to reach another point to improve placement of the piece that is being moved. 

Similar explanations for other applications. 

Every sensible thing is math man. Have you seen that knight thing where that person proved that two opposing knights only on the whole board can be formulaicly proven that the person that goes first can land on the last possible square that hasn't been touched?   

It was a beautiful proof too because they proved it in a way that was easy to understand graphically. But you can be sure it could be turned into math or computer code.

Ergo anything with a precise rule for its moves (so every piece in chess) is going to have geometric limitations and capabilities. Like snowflakes and lightening bolts.

Whether we have to consciously work out the formulas or whether we have good spacial graphic abilities to be able to Know them without much thought doesn't matter, it's still fundamental math at it's core, just like a vacuum cleaner is physics, and a mutated virus is possible evolution.

So, if I am following you correctly, you do not want to claim that much mathematical knowledge is required to learn about triangulation and you do not want to claim that parallel lines, octogons, permutations, and combinations are mentioned very often in chess books?

Think many grandmasters are paying much attention to that sort of thing?

Yes I do think GM's are paying much more attention to math, patterns, logic than I do.

I don't think that chess is somehow connected with math. Both are intellectual activities, that's all.

It's like apple and oranges.

        Both are fruit.

So ... Daniil, your 'somehow connected' is the right expression.

Think many chess books have a chapter on math, math patterns, and/or math logic?

why would they, they don't have to separate the math out, it's mixed in allover natural like.

All chess is geometry mate all geometry is math, get over it.

Ever seen the proof of the a^2 + b^2 = c^2 thing? See things like that commonly "mixed in" with chess instruction?

why would you, pythagoras's theorem is an in credibly specific triangulation tool for finding a side length, something that is never needed in chess.

i think once i used it to plot a pentagram on a plane for an exam but that's only because i forgot the formula that i was supposed to use. never found out if it worked correctly.

Would nearly all of a geometry textbook be "in credibly specific" and "never needed in chess"?

i don't recall ever having a geometry textbook. We had very good teachers that prepared the lessons manually.

Remember seeing the proof of the area of a triangle?

Proof of area of triangle is intuitive. You just make a parallelogram out of it and then divide by half.

If you need proof of area of parallelogram then you just cut out two triangles and make a rectangle out of it. If you need proof of area of rectangle then idk, look up calculus.
