单词	dimensions
释义	Dimensions How many values we need to locate points on a shape. • A point on a line needs only one value so a line has one dimension (1D). Think of the number line: we only need to know the number to place it exactly on the line. • A point on a square needs two values to define it exactly so a square has two dimensions (2D). An example is a graph, we need two numbers to place a dot on it. • A point on a cube needs three values to define it exactly so a cube has three dimensions (3D) • And so on (yes we can have higher dimensions such as 4D and more)
