How Voronoi Diagrams Split a Map by Nearest Place
Voronoi diagrams divide space by nearest points, turning distance into useful regions for maps, services, science, and planning.
Why the Law of Sines Has an Ambiguous Case
The Law of Sines can produce two possible triangles when side-side-angle information does not pin the shape down.
How Offside Lines Turn Soccer Into Geometry
Offside looks like a soccer rule, but close calls depend on geometry, timing, parallel lines, and the exact position of players and the ball.
How Similar Triangles Make Scale Drawings Work
Similar triangles keep angles the same and side lengths proportional, making maps, models, shadows, and scale drawings work.
