Use curves for beauty and angles for strength. — Bernard Leach
Compare an oval to a triangle: Which has more elegance and which has more power? A construction scaffolding structure in Buenos Aires makes a strong visual composition as a result of angular braces, which serve to give it support physically and the yellow patches help to keep your eye moving.
From teepee to pyramids to staircase to bridges — architects and builders and engineers have relied on angles for eternity for their strength & character.
The world around us is shaped with right angles: Our living & working structures have flat ceiling with perpendicular walls. Many of us live in communities based on grids. The sheets of paper we read, monitor screen, shelves — they are fundamentally composed of right angles. These ninety degrees define our modern and postmodern lives.
Angle often carry motion, force, vitality and verve. Rotate a square forthy-five degrees, and it takes on enough attitude to become a warning sign.
Sharp, persistent angles without repose can be jarring or aggressive and unsettling, and purely round forms (circle) are usually boring. However, what we find in tension between the two forces is quite compelling. See how beautiful hard angles are when softened with age and juxtaposed with curved columns from the wall in Parma, Italy. Arches are excellent examples, as they blend angles and curves in a magical and profoundly useful manner.
Angles put us on high alert, which is why graphic designers slap forty-five-degree-angled banners on magazines or websites. Many road signs are on angles for a reason. Angles probably do not make pizza or pie taste better, but they make it an adventure to pick up and eat.
