Which constraint would define the angles and distances between geometric elements?

The correct choice is geometric constraint. Geometric constraints are used to define relationships between geometric elements, such as points, lines, and curves. These constraints help in maintaining the spatial arrangement of the elements by specifying conditions like parallelism, perpendicularity, tangency, and equal distances. When geometric constraints are applied, they ensure that the shape and configuration of the design remain consistent even if dimensions are changed or adjusted.

Dimensional constraints, while important, primarily focus on the size of the features—such as lengths and angles measured in units—rather than their characteristics relative to each other. Numeric constraints relate to quantitative values but do not specifically address the geometric relationships between elements. Spatial constraints, though they may seem relevant, generally pertain to the overall arrangement of objects in space rather than the specific angles and distances that geometric constraints define. Therefore, geometric constraints are the most appropriate choice for establishing the angles and distances between geometric elements.
