"ابعاد" refers to the dimensions or measurements of an object or space. It typically includes length, width, and height, which help to define the size and shape of physical entities. Understanding ابعاد is essential in various fields, such as architecture, engineering, and design, as it allows for accurate planning and construction. In mathematics, ابعاد can also refer to the concept of dimensionality, which describes the number of coordinates needed to specify a point within a space. For example, a line has one ابعاد, a plane has two, and our three-dimensional world has three ابعاد. This concept is crucial in fields like physics and computer graphics.
