sit in 3. figura Stylus rectus, AP,
cujus apex A, pes vero B. Sintque C, D, E.
tria umbrae puincta data, quorum unum
V. 9. D, vicinius stglo reperiatur quam
duo reliqua D, F..
Connectantur 1. duo punita umbre

due perpendiculares Ba, Ba, aequales
altitudini stuer AB. Connectantur rurs
rectae, 2C, aE; aguibus abscindantus
rectae aF, aG, equales distantia apuis
etyer A, a proximo umbrae pundto D.
A punetis autem F, X, 6, ducantur
ad rectas BC, BF, duae perpendiculares,

si producta concurrat cum recta CF, ducatur
ad ipsarum concursum per punctum D
recta KDL; vel si rectae HI, CF. sint eae
ducatur per idem punctum D, ad utramuio
