A 3D object that has all of it's sides slanted inwards; opposite of convex.
A dart.
congruent concave convex
The concave side refers to the side of a curve that is curved inward or "caved in." It is the side that appears to be creating a hollow or depression in the surface. In geometry, concave shapes curve inward, like a cave.
what does empirical mean in geometry
it is the deeper concave offered by zero skateboards
If an object is concave, it means that is contains a surface that curves inward. Eyeglass lenses and bowls, for example, can both be said to be concave.
geometry means lines, segments, and points!!
bent or curved inwards
there is no easier way to learn Geometry
Geometry means earth or land measurements
circumference, chord, cosine, cylinder, cone, concentric, coplanar, convex, concave, compression, collinear hope i helped!
It is an education term that mean it meets the states criteria for geometry.
