graphite breaks by cleavage because the bonds between its atoms are less strong in directions
talc's cleavage is perfect in one direction, basal.
Graphite
Perfect in one direction but often does not show.
When you snap graphite it breaks in perfect triangle shapes. Sources: My science teacher.
Cleavage refers to the tendency of a mineral to break along flat surfaces. Graphite and mica have the same type of cleavage, which is a perfect basal cleavage.

Muscovite has perfect basal cleavage, or book cleavage.
The cleavage of sodium chloride crystals is {100} Perfect, {010} Perfect, {001} Perfect.
Graphite
it probably break apart with cleavage, because the carbon atoms in graphite from sheets that could split apart easily in layers.
perfect
Cobalt has perfect cleavage in all directions.
