Solid has definite shape, distinct boundaries and fixed volumes.So, they are rigid.
Liquid has no fixed shape but has a fixed volume. Liquids flow and change shape, so they are not rigid but can be called fluid. 
Gaseous have no fixed shape and no fixed volume. It is compressible for example LPG, CNG gas, etc.
