Orthometry refers to the measurement of the right angles, lines, and perpendicular distances in a geometric figure. It is a field of study that is essential in engineering, architecture, and design. The term orthometry can be substituted with words such as orthogonal projection, parallelism, and perpendicularity. Orthogonal projection is the projection of an object onto a plane, along lines orthogonal to the plane. Parallelism refers to the state of being parallel or perpendicular, while perpendicularity refers to the quality of being perpendicular or at a right angle. Overall, these synonyms are all related to the concept of orthometry and are useful in expressing measurements and spatial relationships in geometric figures.
