次元の数が2であること
AI overview
Two-dimensional space is a geometric model that represents the physical universe as a flat plane with just two dimensions—like length and width. This simplified model is useful for understanding and visualizing how things work in a reduced form before dealing with the complexity of the three-dimensional world we actually live in.

2次元（にじげん、二次元）は、空間の次元が2であること。次元が2である空間を2次元空間と呼ぶ。 なおここでいう空間とは、に限らず、数学的な一般の意味での空間であり、さまざまなものがある（詳細は「次元」を参照）。
