Which term defines constant, non-numerical relationships between the parts of a geometric figure, such as parallelism or perpendicularity?

• A. Geometric Constraint
• B. Mathematical Modeling
• C. Working Drawings
• D. Model

Answer: (A)

Geometric constraints define constant, non-numerical relationships that govern how parts of a geometric figure relate to each other. They’re about orientation and alignment rather than size—for example, keeping two lines parallel or perpendicular, or ensuring a circle remains tangent to another curve. These constraints stay in effect as you edit other dimensions, so the overall geometry preserves its intended relationships. This differs from mathematical modeling, which uses numeric equations to describe relationships; from working drawings, which specify the actual measurements and views to manufacture a part; and from a general model, which is simply a representation that may not enforce specific geometric relationships. An explicit parallel or perpendicular constraint is exactly what maintains those constant relationships between elements.
