Answer the following statement(s) true (T) or false (F)
1. A perpendicularity tolerance can only constrain rotational degrees of freedom relative to the datum referenced. 2. Perpendicularity can be applied to a planar surface, but not to a feature of size. 3. Where two datum references are used with a perpendicularity tolerance, the tolerance zone is perpendicular to the primary datum reference. 4. 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. 5. A common method used to verify a perpendicularity tolerance (MMC) is to use a height gage.
