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

A trapezoid is convex.

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 = (
Well, isn't that a happy little question! A jeweller's mirror is usually concave, which means it curves inward like a bowl. This helps magnify the reflection and make it easier to see small details while creating beautiful pieces of art. Just remember, whether concave or convex, mirrors always reflect the beauty that's within you.
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.
A convex lens is thicker at the center and thinner at the edges, causing light rays to converge to a focal point. This type of lens is often used in cameras and binoculars. On the other hand, a concave lens is thinner at the center and thicker at the edges, causing light rays to diverge. Concave lenses are commonly used in correcting nearsightedness.
