Which descriptive term applies to rights angles and their interactions?

The term that applies to right angles and their interactions is orthogonal. In geometry, when two lines or planes intersect at right angles (90 degrees), they are said to be orthogonal to each other. This concept is fundamental in various fields, including surveying, engineering, and architecture, as it ensures proper alignment and stability in designs and constructions.

Understanding orthogonality is essential for surveyors when dealing with land parcels, creating subdivisions, or ensuring that structures are built correctly at right angles, which is critical for both functionality and aesthetics. The other terms—oblique, diagonal, and acute—refer to different types of angles or relationships that do not denote the specific 90-degree interaction characteristic of orthogonality. This distinction is important in understanding the foundational concepts in surveying and related disciplines.
