Rigidity and fluidity are inversely proportional to each other and they are characteristic property of different state of matter.
We can clearly say, if a matter show rigidity in its physical property and no fluidity we call that matter as Solids. Other matters such as Liquid and Gas show different type of fluidity and almost no rigidity or rigidity to some extent.
We can say that Rigidity and fluidity are important physical characteristics to define any state of matter.
