    Amorphous solids are said to be isotropic, and crystalline solids are anisotropic for their physical property measurements. Isotropy comes from the Greek word; iso means same and tropos means direction. Anisotropy is observed in crystalline solids because the concentration of the atoms is different in different directions of the unit cell. ... A perfectly arranged cubic crystal structure would be isotropic for some properties like refractive index but would be anisotropic for other properties like photoelasticity.

    but how we can say amorphous solids have same properties in different directions can you explain with a suitable example

    Amorphous solids  are isotropic in nature. It is because there is no long range order in them and arrangement is irregular along all directions. Therefore, value of any physical property would be same along any direction.

    Simply The amorphous solids are an isotropic. They have the same physical properties in all directions due to irregular arrangement. On the other hand, crystalline solids are anisotropic. They have different physical properties in different directions due to the orderly arrangement of constituents.
