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
Effect of Concave Versus Convex Interfacial Geometry on Bond FailureR.J. FEIGAL
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°. Finding a mnemonic device for to remember the difference is easy enough. There...
If a 2-dimensional shape is closed and has 3 or more sides, it's called a polygon in geometry. Once a shape is established as a polygon, the next classification is whether it is a convex or concave polygon. What is a convex polygon? A convex polygon is a shape where all the interio...
Convex Rings Geometry Jacquard Pillowcase is a testament to luxury and historical charm. This cushion cover is meticulously crafted from high-grade 100% polyester, ensuring durability and a soft touch. The embroidered geometric jacquard pattern is a nod to the life in medieval castles and the ...
A concave function is sometimes called ''concave down'' (i.e., the function's secant lines are below the function), while a convex function is sometimes called ''concave up'' (i.e., the function's secant lines are above the function). Thus, concave up vs. concave down is a matter...
How to prove convex set? How to return a polygon to its original position? Explain. What is modern differential geometry? Find: (1-u^2)^3 \times u^2 How would expand this out/ what rules would use to do so ( difference of square type rules etc) What is interpolation and extrapolatio...
This new cross-sectional configuration has natural, convex (of oval geometry) top and bottom (horizontal) planes, and natural, concave (of oval geometry) perpendicular (vertical) side walls. There are no circular (as in the concept where something is round, or considered to be round) surfaces...

Hollow and curved or rounded; vaulted; - said of the interior of a curved surface or line, as of the curve of the of the inner surface of an eggshell, in opposition to convex; as, a concave mirror; the concave arch of the sky. Groove A good feeling (often as in the groove). Co...
