Definitions:

Perpendicularity

A geometric tolerance that specifies the angle between two specified surfaces or features, requiring them to be exactly 90 degrees to each other.

Parallelism

The condition of being parallel; in engineering, the degree to which parts or surfaces are aligned or parallel to each other.

Angularity

Angularity is a measure of deviation or conformity to a specified angle, often critical in part and assembly to ensure proper alignment and function.

Geometric Tolerancing

The specification of allowable variance in the geometric form and location of features on manufactured parts, allowing for precise and repeatable assembly.
