Inscribed Polygons Tilted into Perspective
Square, pentagon, hexagon and circle set upright then foreshortened to the ground
The folio continues the perspective-geometry exercises with polygons inscribed in squares — a smaller square rotated 45 degrees, a pentagon, and a hexagon with a circle — each then shown tilted down toward the ground with sight-lines converging to one or two eye positions. A brief note instructs to first make the hexagon inside the circle, and the single labeled eye position is marked r. Faint pencil repetitions of the same figures run down the right side of the sheet.

Polygons inscribed in squares: rotated square, pentagon, hexagon
A square holds a half-size square rotated 45 degrees whose corners meet the larger square's bisectors; another square inscribes a pentagon touching top and dividers; a third roughly inscribes a hexagon and a circle. The note directs that the hexagon be made first inside the circle.
The inscribed figures tilted down to the ground
Beneath each square the same figure is drawn vertically compressed, as though tilted away and downward onto the ground, with sight-lines from the base converging to two different eye positions, one over the square and one shifted far to the right at a very acute angle. The second eye position is labeled r.
