Joining a Larger and a Smaller Square
A construction headed "Eleventh," with further untranscribed figures
A geometry page headed with the reference "Eleventh," pointing to a proposition, and carrying a construction that joins a larger and a smaller square, annotated 4, 6, 6. Beyond the two transcribed notes the sheet is filled with further figures in pen - divided straight lines (one marked as a whole divided into parts) and triangles with proportionally subdivided bases - whose numeral labels are not included in the transcription.
