GD&T Orientation (Angularity, Perpendicularity, Parallelism)

[@ThriftMedusa]

At 05:33 , how to interpret perpendicularity in reference to B ( I got the A but why are using secondary datum B ? )

[@joshuadaniel9987]

@5.33 the B datum not perpendicular, it perpendicular to C datum

What is shorter side of corner in angular tolerances?

Good video, Angle 137.34 should be given to cylinder Axis line right, but you have given to cylindrical surface
