Concave means bending inward, convex means bending outward.
Concave . . .
- thinnest in the middle
- thickest around the edge
- holds water
Convex . . .
- thinnest around the edge
- thickest in the middle
- water runs off
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
A non convex is a concave and a convex is differently shaped
concave
A trapezoid is convex.
convex
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
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.
A non convex is a concave and a convex is differently shaped
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 curves in (like a cave) = ) and convex curves out = (
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.
Concave surfaces are inwardly curved, causing light to be focused towards a single point (e.g., a concave mirror), resulting in a real image. Convex surfaces are outwardly curved, causing light to be spread out or dispersed, resulting in a virtual image. In the dark, a concave surface may appear darker as it focuses light away, while a convex surface may appear lighter as it scatters light.
Concave lenses are thicker at the edges then at the middle. A Convex lens is a lens that is thicker in the center than at its edges.
A concave lens is a lens in which the ends are thicker than the middle, rather shaped like this ---> )( A convex lens is a lens in which the ends are thinner than the middle, shaped like the following ---> ()
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
It can be convex or concave.
