This is useful to prove theorems such as Desargues’ theorem for pencils of conics. We will also be studying metric projective geometry which will allow us to dicuss about circles, orthogonality, angles, etc. in the projective plane. This will be used to on one hand, study classical results such as Euler’s circle and, on the other hand, to prove a more advanced result, Steiner’s porism. To see this theorem, algebraic geometry is generally used but on this project we will study it under the projective geometry framework.40 p.application/pdfcatcc-by-nc-nd (c) Tània Tomàs Ripollés, 2019http://creativecommons.org/licenses/by-nc-nd/3.0/es/Geometria projectivaTreballs de fi de grauSeccions còniquesGeometria analíticaGeometria algebraicaProjective geometryBachelor's thesesConic sectionsAnalytic geometryAlgebraic geometryinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
