Primary is the sequence of amino acid in polypeptide chain. secondary is the ordered arrangement of amino acids in localised area of a polypeptide chain. Tertiary is three dimensional arangement

Primary is the amino acid sequence, secondary is the 3D shape of individual segments (like alpha-helices + beta-sheets) and tertiary structure is the globular shape of the whole protein.
