Carroll diagrams use two headings that are the opposite of one another (mutually exclusive), e.g. ‘has at least one triangular face’ and ‘has no triangular faces’ ‘is a prism’ and ‘is not a prism’ ‘is regular’ and ‘is irregular’ ‘has at least one pair of parallel faces’ and ‘has no pairs of parallel faces’.
