Amorphous solid can also be called:
(i) pseudo solids
(ii) true solids
(iii) supercooled liquids
(iv) supercooled solids

Solution
(i) pseudo solids
(iii) supercooled liquids
Explanation:
The structure of amorphous solids is similar to that of the liquids. They have a tendency to flow like liquids, though very slowly. Therefore, sometimes they are called pseudo solids or supercooled liquids.
