How to determine if a polygon is concave, convex, regular or irregular
Adjective concave (comparative more concave, superlative most concave) Curved like the inner surface of a sphere or bowl. (geometry, not comparable, of a polygon) Not convex; having at least one internal angle greater than 180 degrees.
A concave is any line or surface that curves inward. (This line is a concave.) A convex is any line or surface that curves outward. (This surface is a convex.)
Concave lenses focus light inside the curve of the lens, while convex lenses focus light using the outer curve. A lens that curves like a āCā (no flat side) is both concave or convex, depending on which side of the lens you view from.
Define concave. concave synonyms, concave pronunciation, concave translation, English dictionary definition of concave. concave left to right: biconcave, plano-concave, and concavo-convex lenses adj. Curved like the inner surface of a sphere.
Concave describes an inward curve; its opposite, convex, describes a curve that bulges outward. They are used to describe gentle, subtle curves, like the kinds found in mirrors or lenses.
Examples of this include intersecting concave and convex surfaces and vertical sculpted features on the front fascia, which are balanced by the horizontal headlamps.
Illustrated definition of Concave: Curved inwards. Example: A polygon (which has straight sides) is concave when there are dents or indentations...
