Geometría, authored by Ximena Carreño Campos and Ximena Cruz Schmidt, is a comprehensive educational text widely used in Chile and Latin America for secondary and university-level preparation. Published by Arrayán Editores (and later McGraw-Hill), the work is designed to bridge the gap between theoretical Euclidean geometry and practical problem-solving. Structure and Educational Approach
The book follows a structured pedagogical model aimed at progressive learning. Each chapter typically includes:
Basic Content Outlines: A summary of essential definitions and theorems.
Solved Exercises: Step-by-step demonstrations showing multiple ways to approach a single problem.
Proposed Exercises: Practice sets with provided solutions for self-assessment.
Multiple-Choice Sets: Targeted questions to prepare students for standardized exams.
Comprehensive Final Test: An appendix featuring a 60-question multiple-choice exam covering all book contents. Key Topics and Chapters
The work is divided into nine primary sections covering the foundations of plane and solid geometry:
Basic Elements of Geometry: Lines, points, planes, and angles.
Isometric Transformations: Translations, rotations, and symmetries. geometria ximena carreno pdf work
Triangles: Congruence, properties, and special segments (altitudes, medians, etc.).
Geometry of Proportions: Similarity (homothety) and Thales's theorem.
Quadrilaterals: Classification and properties of parallelograms and trapezoids.
Circles and Circumference: Perimeter, area, and angular relationships.
Polygons: Interior and exterior angles, and regular polygon properties.
Geometric Loci: Sets of points satisfying specific conditions (Locus).
Geometric Bodies: Introduction to 3D geometry, including volume and surface area of prisms and spheres. Supplementary Material
The text often includes a special chapter or annex dedicated to the use of educational software for solving geometric problems, modernizing the traditional approach. While primarily a physical textbook, digitized versions (PDFs) are often sought by students on platforms like Scribd and El Solucionario for study and reference.
Geometría by Ximena Carreño Campos and Ximena Cruz Schmidt is a comprehensive educational text widely used in Latin America, particularly in Chile, for secondary education and university preparation. Published by houses such as Arrayán Editores and McGraw-Hill, the book is designed to build critical thinking and analytical skills through the lens of Euclidean geometry.

The work is structured into thematic chapters that cover the fundamental pillars of geometry:
I. Basic Elements of Geometry: Introduction to fundamental concepts like points, lines, and planes.
II. Isometric Transformations: Detailed study of translations, rotations, and reflections in the plane.
III. Triangles: Exploration of congruence, similarity, and special triangle properties.
IV. Geometry of Proportions: Covering Thales' theorem and proportional relationships in geometric figures.
V. Quadrilaterals: Classifications and properties of four-sided figures.
VI. Circle and Circumference: Extensive coverage of circular properties, tangents, and secants.
VII. Polygons: Examination of regular and irregular polygons, interior/exterior angles, and diagonals.
VIII. Geometric Loci: Study of sets of points satisfying specific conditions (e.g., perpendicular bisectors). Section A: Foundational Lemmas (without proof, but with
IX. Geometric Bodies: Analysis of three-dimensional figures, volumes, and surface areas. Educational Methodology
The text is known for its "learn-by-doing" approach. Each chapter typically includes:
Schematic Summaries: Basic content outlines to reinforce theory.
Solved Examples: Step-by-step walkthroughs showing multiple ways to solve a single problem.
Proposed Exercises: Practice sets with solutions provided at the end of the book.
Multiple-Choice Tests: A final 60-question comprehensive exam to simulate standardized tests.
Computational Applications: Guidance on using software like Cabri Géomètre to solve geometric problems. Availability and Format

Many modern architecture schools have reduced their geometry hours, assuming students will learn via SketchUp or Rhino. Consequently, graduates enter the workforce unable to draw a correct section or scale a perspective by hand. The PDF serves as a replacement curriculum for self-learners and recent graduates who realize their formal education left a gap.
