EUTOCII COMMENTARIA IN CONICA. 299 sin, ut in tertio casu, sic quoque FAj A/1, si productae erunt in infinitum, sectioni adpropinquant et ad distantiam omni data minorem perueniunt, EZy ZH autem ad Z partesque ei propinquas intra angulum positas sectioni propinquae sunt, productae uero magis a sectione distant; nam quam nunc^) habent distantiam, ea omni data est minor. iam rursus, ut in quarta figura, asymptotae sint EZ, ZH. itaque sic quoque manifestum est, FA sectioni propiorem esse quam EZj siue EZ rectae FA parallela est siue cum FA concurrit. et si punctum concursus supra rectam per Z sectionem contingentem ^) positum est, sectionem secat, sin punctum concursus in spatio inter contingentem angulumque positum est, sicut etiam ZHj eodem modo, quo supra, @H^) a sectione non distabit interuallo, quod omni dato minus est. ergo FA sectioni propior erit quam EZ.
