Three Triples of Segments: Direct Proportion
Three groups of three measured segments, their relation marked 'direct'
On this leaf three triples of segments are again measured - a 18, b 6, c 2 against d 12, e 6, f 3, with h 8, g 4, c 2 - but the relation is now marked 'direct' (dirette), with the terms further annotated 'lesser' (minore) and 'equal' (equa). The page pairs with the facing verso to contrast direct and indirect proportion. Several lines of mirror-script prose below the diagrams are not included in the source transcription.

Three triples of segments, direct proportion
As on the facing verso, three groups of three segments are measured - a 18, b 6, c 2 against d 12, e 6, f 3, with h 8, g 4, c 2 - but here the relation is labelled 'direct' (dirette). The words 'lesser' (minore) and 'equal' (equa) annotate the comparison of the terms.
Untranscribed notes below the diagrams
Beneath the segment diagrams the leaf carries several lines of mirror-script that the source transcription does not include. Their content is not given here and is not read from the image.
