In the competitive mathematics community, particularly within the Ibero-American and Spanish-speaking olympiad circuits, Ximena Carreño is a recognized problem poser and geometry specialist. While not as globally ubiquitous as Coxeter or Prasolov, her compiled PDFs (often circulated as "Geometria - Ximena Carreño") serve as a crucial bridge between elementary Euclidean geometry and the rigorous demands of national and international olympiads (IMO, OIM, CONAMAT).
Her work is characterized by:

In the vast landscape of architectural theory and design education, certain pedagogical materials transcend their original purpose to become legendary references. One such resource is the collection of exercises and principles associated with Ximena Carreño, often searched for under the keyword "geometria ximena carreno pdf work".
For architecture students, self-taught designers, and CAD professionals, finding and understanding this PDF is akin to discovering a master key to spatial reasoning. But what exactly is this document? Why has it become a cornerstone of foundational design? And where can its principles be applied? A traditional architectural plan is linear: you begin
This article provides a deep dive into the Geometria Ximena Carreño PDF work, exploring its content, methodology, and lasting impact on design pedagogy.
A traditional architectural plan is linear: you begin at the entrance and move through the floor plan in a prescribed sequence. Carreño’s Geometria PDF refuses such linearity. The work is not meant to be “read” from page 1 to page N; rather, it is a constellation. Each page is a fragment of a larger, non-Euclidean structure. One page might present a strict orthogonal grid reminiscent of Le Corbusier’s Modulor, while the next page dissolves into radiating concentric arcs that suggest a baroque church floor or a sonic resonance chamber. impossible city). The document is
The affordances of the PDF become critical here. The ability to jump between non-consecutive pages, to zoom into the hairline fracture of a line, or to view two pages side-by-side on a monitor turns the act of viewing into an act of virtual navigation. Carreño anticipates this. She designs her geometries to reward the zoomed-in detail (where a line reveals itself as a thin white gap between two blacks, creating a negative-space threshold) as well as the zoomed-out overview (where individual pages coalesce into a larger, impossible city). The document is, in effect, a blueprint for a mental architecture—a building that exists only in the cognitive space between the viewer’s perception and the PDF’s pixels.
