Circle divisions and a hatched triangle (geometry)
Compass diagrams dividing circles into sectors, with untranscribed notes.
The upper margin carries compass-drawn circle diagrams: one circle crossed by a diameter with an inscribed curved figure, and another divided into radial sectors like the petals of a rosette above a point. At the right a large triangular wedge with a curved side is filled with parallel hatching. Several lines of Leonardo's mirror-script accompany the figures but were not transcribed in this bundle, so their content is not reproduced here.

Circle divided into radial sectors
A circle near the top of the sheet is divided by straight lines from its centre into a fan of radial sectors, resembling the petals of a rosette, and runs down to a single point below. Beside it a second circle is crossed by a diameter and holds an inscribed curved figure.
Hatched triangular wedge
At the upper right a large triangular wedge with one curved side is filled with fine parallel hatching. A few faint letter-labels sit along its edges, but the writing on the page was not transcribed here.
