Why did the gothic master builders use geometric lines and patterns in their designs

Gothic architecture is a European architectural style that respects height and exhibits a dynamic and delicate aesthetic. Although its origins are French, the Gothic style can be seen in churches, cathedrals and other modern buildings in Europe and beyond. Gothic architects used flying buttresses for support to build larger, more fragile buildings with thinner walls. These stone structures made it possible for architects to create sky-high cathedrals and churches that evoked etherealism and reached the heavens.

nope! and if it is, i'd rather not know lol
