What is the logical reasoning used to solve this puzzle?

All the respective parts of the square add up to 20. E.g. bottom triangle 6 + 3 + 4 + 7, up triangle 3 + 6 + 3 + 8, right triangle 2+ 6 + 4 + 8 and so last triangle 4 + 6 + 9 + missing number 1

I approached the problem in a different way
There is a relationship between the two right
and two left shapes.
For the two right:45+101=146(1+4+6)=11
58+116=174(1+7+4)=12(11&12 differ by 1)
For the two left:35+13=48(4+8)=12
37+12=49(9+4)=13(12&13 differ by one)so according to this logic path the number should be 1
