To play along - yes, some truths are necessary truths. In that they are by definition true. If we define a triangle as a 2D shape with 3 angles, then it's absolutely true to say that a 2D shape with 3 angles is always a triangle.
Thats a definition, not a truth. If we say 'ABC' = 'triangle', then ABC is synonymous with triangle.
