If you play the Cm pentatonic, you can play all the notes in that scale. If you're talking about chords, you gotta match the scaledegree.
The pentatonic scale has 5 degrees. Im IImaj IIIsus IVquartal and Vsus2
Which pretty much tells you that if you wanna play a chord in C, you'll do a minor triad for example.
The degrees are:
I - C
II - D#
III - F
IV - G
V - A#
