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.
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 ---> ()
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.
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.
