Well, first of all triangles can't be quadrilaterals because qaud means four and tri means 3. A triangle is a polygon. A triangle can not have any less or any more than 3 sides, but not all of them have to be the same length, so therefor it can defenitally not be a quadrilateral because it only has 3 sides and it doesn't have to be equal on all of the sides.
