Which term describes a three-dimensional drawing made of equal angles of 120 degrees?

The term that describes a three-dimensional drawing made of equal angles of 120 degrees is isometric projection. In isometric projection, the three coordinate axes are equally inclined to the plane of projection, resulting in angles of 120 degrees between them. This projection technique allows for the representation of three-dimensional objects on a two-dimensional plane while maintaining the proportions of the object.

Isometric drawings are particularly useful because they enable viewers to visualize the object's dimensions and spatial relationships without distortion, making it easier to understand the design. The parallel lines in an isometric projection remain parallel, enhancing clarity and detail in the drawing.

Other projection types differ in how they represent three-dimensional objects. For instance, perspective projection mimics human visual perception, providing a more realistic representation but distorting dimensions. Orthographic projection, on the other hand, involves projecting parts of the object onto perpendicular planes, which does not provide the 120-degree angle between axes characteristic of isometric projection. Axonometric projection is a broader category that includes isometric, dimetric, and trimetric projections, but it does not specifically refer to the equal angles that define isometric projection. Thus, the best fit for the question is isometric projection, based on its unique angle characteristics.
