concave
convex
A trapezoid is convex.
A non convex is a concave and a convex is differently shaped
Concave, because you can connect the corners from the outside.
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
concave and convex refer to the curve of the mirror. if it is concave, it curves in at the middle, like a 'cave'. if it is convex, it curves out at the middle, like an eye. think of a spoon - one side is convex, the other is concave. this curve will affect the image the mirror shows.
concave (bulges inward) convex (bulges outward)
Convex lenses protrude or curve out, concave lenses curve in, like a cave...
A concave polygon has lines that curve inwards whereas a convex polygon has lines that curve outwards and they are found on and inside spheres
Concave lenses curve inwardly.Convex lenses curve outwardly.* See related links.
contact lenses are concave because their sides curve inward
Convex lenses are curved inward. Concave lenses curve outward.
Concave means inward and Convex means outward, therefore "concave right scoliosis" means that there is an inward curve to the right in the spine
An inward curve is called concave, while an outward curve is called convex
concave
Lenses are either concave or convex. Concave lenses curve inward from both sides, and convex lenses curve outward one side and inward on the other. Concave and convex lenses change the image to be able to see from close or far distances.These are used for glasses, magnifying glasses, and telescopes.
