When three vectors form a closed triangle graphically, it means the sum of these vectors is zero. The largest angle in any triangle cannot exceed 180°, as this is the straight angle, beyond which the vectors would not form a closed triangle but would start to 'open up'. Therefore, the largest enclosed angle between any two vectors in such a scenario cannot be greater than 180°.
