There’s a “cave” in concave, and caves are inward curvatures. That doesn’t work as well for convex, but if you can recall what we said for concave, all you need to do is remember that convex is the exact opposite. Examples of concave vs. convex The main parts of the complex ...
Conversely, a curve that bulges outward or has a convex shape is said to be convex. Convex curves have a positive curvature, and their second derivative is positive. Examples of Concave Curves The Parabola The parabola is a classic example of a concave curve. It is a symmetrical curve that...
Concaveandconvexare literal opposites—one involves shapes that curve inward and the other involves shapes that curve outward. The terms can be used generally, but they’re often used in technical, scientific, and geometric contexts.Lenses, such as those used in eyeglasses, magnifying glasses, bin...
In geometry, an important distinction is made between shapes that are convex and those that are concave. A convex shape is one in which all interior angles are less than 180 degrees. A concave shape, on the other hand, is one in which at least one interi

Convex polygons have specific formulas that are used to calculate the area of the polygon using easily measurable parts like length, width, and height. The following examples show two convex polygons and the formula that calculates their area. These two polygons are convex because their angles ...
