Question

define convex and concave​

Answer 1

Answer:

Defination of concave:

Concave describes shapes that curve inward, like an hourglass.

Convex describes shapes that curve outward, like a football (or a rugby ball).

If you stand in front of a concave mirror, your reflection will look taller. If you stand in front of a convex mirror, the opposite will happen—your reflection will appear shorter.

Definition of Convex:

A convex shape is the opposite of a concave shape. It curves outward, and its middle is thicker than its edges. If you take a football or a rugby ball and place it as if you’re about to kick it, you’ll see that it has a convex shape—its ends are pointy, and it has a thick middle.

Mary’s design proposal included a lot of convex lines.

Just like concave, convex can be used as a noun for a surface or line that curves outward, and it also has a use in geometry, where it describes a polygon with interior angles less than or equal to 180°.

Answer 2

Answer:

Concave means "hollowed out or rounded inward" and is easily remembered because these surfaces "cave" in. The opposite is convex meaning "curved or rounded outward." Both words have been around for centuries but are often mixed up.
