What would be the equivalent of the word quadrant when referring to 1/2 and 1/8 of an area? I'm looking for a more specific term than simply a half.
To give more detail, I'm looking for a term which can refer to a node of a binary tree data structure. In a quad tree data structure, you can refer to each node as a quadrant. I'm looking for the equivalent reference in a binary tree. It would be incorrect to refer to a node in a quad tree as a quarter or a quarter-plane, likewise for a binary tree it would be incorrect to refer to a node as a half or half-plane.
