Question: 1 / 400

Which term describes a figure having exactly two dimensions?

Tridimensional

Bi-dimensional

The term that describes a figure having exactly two dimensions is "bi-dimensional." This term comes from the prefix "bi-" which means two and is used in contrast to other terms that refer to additional dimensions. A bi-dimensional figure occupies a flat surface, represented by length and width, but has no thickness or height. Common examples of bi-dimensional figures include squares, rectangles, circles, and triangles. Understanding the concept of dimensionality is crucial in various fields, such as geometry, design, and spatial reasoning.

In comparison, "tridimensional" refers to objects with three dimensions (length, width, and height), "monodimensional" describes one-dimensional figures which only possess length, and "quadrimensional" pertains to hypothetical or theoretical constructs involving four dimensions.
