Where a perpendicularity tolerance is applied to a width, the feature control frame is placed ____________________ (or beside) the size dimension.

A general angular tolerance or an angular dimension invokes a(n) ____________________-shaped tolerance zone.

Where perpendicularity is applied to a width at RFS, the tolerance value defines the ____________________ between the tolerance zone planes.

Perpendicularity can be applied to a planar surface, but not to a feature of size.

A perpendicularity tolerance can only constrain rotational degrees of freedom relative to the datum referenced.

____________________ is the condition where a surface, axis, or center plane is exactly 90 degrees to a datum plane or axis.

Define a precision square and briefly explain how it is used.

When a perpendicularity tolerance is applied to a planar surface, the deviation is verified by finding the distance between two parallel planes that all of the points of the surface are located within.

What are the four common real-world applications of a perpendicularity tolerance on a drawing?

In certain applications, part function requires the perpendicularity deviation of a surface to be defined relative to a(n) ____________________.

What are the two common tolerance zones for a perpendicularity tolerance?

Where two datum references are used with a perpendicularity tolerance, the tolerance zone is perpendicular to the primary datum reference.

Where perpendicularity is applied to a planar surface, what are the four conditions that apply?
