concave
A trapezoid is convex.
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.
The two types of curved mirrors are concave and convex mirrors. Concave mirrors curve inward and can create both real and virtual images, while convex mirrors curve outward and only produce virtual images.
Concave shapes curve inward, like a cave, while convex shapes curve outward, like a bump.
Convex shapes curve outward, like a dome, while concave shapes curve inward, like a cave.
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
Lenses can be concave or convex depending on their shape. Concave lenses curve inward and are thinner in the center, causing light to diverge. Convex lenses curve outward and are thicker in the center, causing light to converge. Glasses can have either concave or convex lenses, depending on what vision correction is needed.
Concave lenses curve inwardly.Convex lenses curve outwardly.* See related links.
Concave shapes curve inward, like a cave, while convex shapes curve outward. To distinguish between them, you can look at the direction in which the shape curves - concave curves inwards, while convex curves outwards.
The architectural term you are referring to is an "ogee." It describes a type of molding that has a profile featuring a concave curve flowing into a convex curve.
contact lenses are concave because their sides curve inward
Convex lenses are curved inward. Concave lenses curve outward.
