"Perpendicular lines are two lines that intersect at 90° angles." is describing what perpendicular lines are. Is this a theorem or a definition? "All right angles are congruent." is telling you something about all right angles. Is it defining for you what right angles are, or is it just telling you something about right angles?
Statement 1 is true so it's a postulate.
Statement 2 is a definition.
