### The definition of "consistent"

Hello,

I have a question about the definition of "consistent", I've seen 3 places where it appears (there are more for sure), which I cannot see if they have same meanings:

1. Assignment4 problem5, "to prove the value of pi_dot is consistent", I could understand the explanation after that though.

2. Slide 7 of lecture1005, "for a set of virtual displacements to be consistent some constraint equations should hold".

3. In the answer from Dan to Milad's question "How Constraints are satisfied", the GCON in some configuration q may or may not be consistent.

Thanks.
