concave definition

Is convex a word?
Convex has the word in it (because it is vexing that this word is hard to remember), and means “curved or rounded outward.” Neither word is particularly recent; concave has been in English since the 15th century, and convex since the 16th.

What is a concave lens?
Concave lenses are used in eyeglasses for people who are nearsighted (those who have trouble seeing things that are far away). Convex lenses are used in glasses for people who are farsighted (those who can’t see things very well up close).
What is the difference between convex and concaveconvex?
We instead provide you with serious tools, such as the etymology of each word, and thus allow you to distinguish between them as a scholar would. So if you need to tell the difference between concaveconvex simply remember that convex comes from the Latin word convexus, which may mean either “convex” or “concave” or … wait a minute.

⚡️Quick Summary

Concave means curving inward—like the shape of the inside of a bowl. Convex means curving outward—like the shape of the outside of a contact lens. To put it another way, a concave shape can be filled, while a convexshape creates a dome. dictionary.com

What Does Concave Mean?

Concave means “curving inward” or “hollow and curved,” like the inside of a bowl, or, more technically, the inside of a partial sphere. A crater is roughly concave. dictionary.com

What Does Convex Mean?

Convex means “having a surface that is curved or rounded outward,” like the outside of a contact lens (the part that a person touches when putting it on their eye). A mound is roughly convex. How do you measure that outward curve though? Learn the ins and outs of the ratio pito find out. dictionary.com

Concave vs. Convex Lenses

Concave lenses—those that are thicker around the edges than they are in the center—disperse light rays, which can have the effect of making things look smaller or farther away. Convex lenses—those that dome outward and are thicker in the center than they are around the edges—make light rays converge. Convex lenses have the opposite effect of concav

Concave vs. Convex Mirrors

Convex mirrors have the effect of making things look farther away and allowing for a field of view that’s wider than the one you would normally be able to see. Most cars have convex passenger side mirrors that allow the driver to see objects that would normally be in the vehicle’s blind spot. This is why the mirror says Objects in mirror are closer

Concave vs. Convex Polygons

In geometry, concave has a more specific meaning that’s used to describe the shape of a polygon (multi-sided figure) that has at least one interior angle greater than 180 degrees (translation: it’s a shape with at least one inward angle). Convexpolygons are those in which all the angles are no greater than 180 degrees—meaning that none of them poin

How to Use Concave vs. Convex

Here’s the best way to remember the difference: concave things curve or turn inward, like the inside of a cave. Convex things curve or turn outward—regular hexagons are excellent examples of convexpolygons. Of course, generally speaking, some shapes could be considered both concave and convex depending on how you’re looking at them. In a semicircle
