Which symbol denotes an angularity tolerance in GDandT?

• A. A circle with a cross
• B. A triangle symbol with a defined angle
• C. A square symbol
• D. A dashed line

Answer: (B)

The symbol that denotes an angularity tolerance in GD&T is represented by a triangle symbol with a defined angle. This symbol is crucial for specifying the relationship of a feature's orientation to a datum or a reference line at a precise angle. Angularity is used to control how much a feature can deviate from its true angle, which is essential in applications where the fit and linkages between parts rely on precise angular relationships.

The triangle symbol specifically indicates that the tolerance being applied is in relation to an angle, allowing designers and engineers to communicate their requirements clearly. By defining this relationship through the angularity symbol, it becomes easier to enforce consistent manufacturing quality and assembly processes.
