A Line Divided at Points a, b, c
Pencil study of proportional division, gone over in pen
The transcription gives only the sheet's catalogue number 101 and the diagram's letter labels a, b and c, the raw material of the notebook's studies on dividing a line into proportional parts. The figures are in pencil later reinforced with pen. The leaf also carries additional mirror-script annotation that the transcription does not include. It belongs to the run of Euclid-based geometry exercises in Manuscript K.

Segment marked a, b with the point c
The transcription records the labels a and b together with a third point c. Lettered segments of this kind are the basis of Leonardo's proportional-division exercises across these pages. No numerical values are attached to this particular figure.
Further untranscribed notes
Beyond the three letter labels the sheet bears additional lines of Leonardo's mirror-script that the transcription does not include. Their content is not given here and is not reproduced.
