geometrical

/ˌʤiəˈmɛtrɪkəl/

Something that's geometrical is made up of simple shapes and lines, like the geometrical details in your little sister's painting of a cat, with its triangle ears and egg-shaped body.

You might admire the geometrical style of an Art Deco house or the geometrical nature of a piece of honeycomb, segmented into tiny hexagons. In most cases, you can use the adjectives geometrical and geometric interchangeably. They both come from geometry, the branch of mathematics that involves measuring the space inside shapes, like calculating a circle's circumference or the area of a polygon. The Greek root, geometria, means "measurement of earth or land."
