Geometria (film)

Geometria (film) is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Geometria (film) rather than just read about it. In short: Geometria is a 1987 short fantasy horror comedy film written and directed by Guillermo del Toro. It is based loosely on Fredric Brown's short story "Naturally", which was originally published in Beyond Fantasy Fiction and later reprinted in the short story collection Honeymoon in Hell.

Key takeaways

  • Geometria (film) belongs to mathematics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Geometria (film) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Geometria (film) from memory before moving on to harder problems.

Reference excerpt

Geometria is a 1987 short fantasy horror comedy film written and directed by Guillermo del Toro. It is based loosely on Fredric Brown's short story "Naturally", which was originally published in Beyond Fantasy Fiction and later reprinted in the short story collection Honeymoon in Hell. Geometria was shot in Guadalajara, Jalisco in Mexico. It is the tenth short film del Toro directed, though all but 1985's Doña Lupe remain unreleased. Del Toro was not satisfied with the original cut of the film, and said that he was not able to finish it the way he wanted to at the time. A director's cut of the film, slightly shorter than the 1987 cut, with a new music score composed by Christopher Drake was included on The Criterion Collection's 2010 release of del Toro's 1993 feature film debut, Cronos. In the film, a high school student has repeatedly failed his geometry exams. He summons a demon to fulfill his wishes, in hopes of both passing the exams and of resurrecting his father. The demon twists the meaning of his wishes to inflict horror on the student. He then explains that the student's poor understanding of geometry has doomed him. Instead of drawing a protective pentagon (as per instructions), the student had drawn a hexagon. Which is useless for protecting him.

Plot A Mexican widow (Guadalupe del Toro) receives a letter from the high school attended by her son (Fernando Garcia Marin). It informs her that the boy is about to fail his geometry exams for the third time. The woman berates her son, then turns on the television, refusing to speak to him. The boy leaves the room, vowing that he will never fail geometry again. The boy resorts to using black magic in order to pass the exam. In a dark room, he reads from a tome of sorcery, which states, "As a protection for the invocation of a major demon, place yourself inside a pentagon drawn with your own blood. This pentagon will be your only protection." The boy proceeds to follow these instructions. While the woman sits in the living room, watching a pastiche of The Exorcist, she hears her son screaming from the next room. When she enters, she finds him standing in the middle of the bloody seal. He shouts a warning, telling her that the pentagon is his only protection. A glowing portal opens in the wall, and a demon (Rodrigo Mora) steps through. The boy asks the demon to grant two wishes. The first is that he will not fail geometry again. The second is the return of his father, Francisco, who died in an accident three months ago. The demon complies with the latter, causing Francisco to materialise immediately. However, he is now a mindless zombie. Francisco kills and eats his wife, while their son looks on in horror, unable to step out of the pentagon for fear of losing its magical protection. The demon commands the boy to surrender, but he refuses to give in, saying that he cannot be harmed while he stands within the pentagon. The demon reasons that he has already granted one of the boy's two wishes: his family is together again. He also points out that what the boy has drawn is not a pentagon, but a hexagon, which offers no magical protection whatsoever. The demon muses that the boy's other wish has also been granted: he will never fail geometry again. Francisco approaches his son from behind and takes hold of his head, tilting it backwards. The boy laments the unfairness of his situation. The demon agrees, and reaches out a hand to take hold of his throat. The screen fades to black as ripping sounds are heard.

Reception Bloody Disgusting said, "Geometria makes for an inspiring short from a filmmaking standpoint, as well as a humorous piece of gruesome horror for the casual fan."

Worked examples

Example 1 — a first encounter with Geometria (film)

Start with the simplest possible case. Write down what Geometria (film) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Geometria (film) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Geometria (film) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Geometria (film)

In research
Geometria (film) appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Geometria (film) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Geometria (film) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1980s dark fantasy films, 1980s demon films, 1980s high school films, so understanding it makes those chapters shorter.
In everyday life
Look for Geometria (film) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
