In L2 space c2 = a2 + b2

If we draw a large triangle on a curved surface like the Earth then the Pythagorean theorem won't work. But if we shrink the triangle down the curvature becomes less and less until it approaches being completely flat and the Pythagorean theorem works again.
If we draw a large triangle in LP space where P<>2 then the Pythagorean theorem also won't work. The difference is that it still won't work even if one shrinks the triangle down to nothing.
My question is what happens in the curved space of a black hole? Is it like the curved surface of the Earth or like the intrinsic curvature (no, that probably isn't right. maybe 'intrinsic distortion from L2 space) of LP space? Does a small enough piece of space near a black hole behave like regular flat L2 space (yes i know, technically it would be minkowski space but i am only interested in the space component and nonrelativistic speeds)
