Architecture

building plans, room layouts

Floor plans are pure 2D shapes — rectangles, polygons, circles. Roof slopes are right triangles; arches are circular segments.

Art

composition and perspective

Composition relies on triangle-of-thirds and golden-ratio rectangles. Picasso's cubism literally decomposed faces into shapes.

Sports

pitch markings, court dimensions

Football pitch (rectangle 100×64 m), basketball key (trapezoid), running track (rectangle + 2 semicircles) — every game inherits its arena from geometry.

Packaging

box sizes for shipping

Cereal boxes are cuboids, soft-drink cans are cylinders, ice-cream cones are cones. Container shape decides shipping cost per item.

Crafts

cutting fabric, making patterns

Quilting, origami and tile patterns work because shapes tessellate predictably — squares, hexagons and equilateral triangles fill space without gaps.

Robotics

navigation through space

A robot vacuum maps your room as polygons and computes the shortest path that covers each polygon — shape recognition under the hood.
