Having an outline or surface curved like the exterior of a circle or sphere,
  1. Having an outline or surface curved like the exterior of a circle or sphere

  2. (of a polygon) Having only interior angles measuring less than 180°

  1. curving or bulging outward
  2. (convexness) convexity: the property possessed by a convex shape
  3. In mathematics, a real-valued function defined on an interval (or on any convex subset of some vector space) is called convex, concave upwards, concave up or convex cup, if for any two points and in its domain X and any ,
  4. In Euclidean space, an object is convex if for every pair of points within the object, every point on the straight line segment that joins them is also within the object. ...
  5. curved or bowed outward like the outside of a bowl or sphere or circle; (not comparable) (Of a set of points) such that for any two points in the set, every point between those two points is also in the set; (not comparable) (of a real-valued function on the reals) such that the value at any ...
  6. An awning configuration characterized by a series of parallel bows in the shape of a convex curve. It produces a radius shape with flat ends.
  7. A term used to describe a lens side that is outwardly and usually spherically curved.
  8. curved like the outer surface of a sphere
  9. Surface, bending slightly outwards. See concave.
  10. A convex polygon or polyhedron is one where any line segment drawn from a point inside the shape to another point inside the shape, will lie entirely within the shape.
  11. A region in the plane, in Euclidean space, or in some other geometry with lines such as hyperbolic space, is convex if it always contains the line segment connecting two points if it contains the two points themselves. ...
  12. comes from the two Latin roots com (with) and vehere (to carry) and literally means "to bring (carry) together". The word seems to be a variation of "convection" from the same roots. Vehere is also the base root in vector, and of course, vehicle. ...
  13. A subset K of a Riemannian manifold M is called convex if for any two points in K there is a shortest path connecting them which lies entirely in K, see also totally convex.
  14. curved or bulging outwards, in eucalypts usually referring to the disc of the fruit where the outer wall is curved outwards [image]
  15. Having a surface that is curved or rounded outward.
  16. A term to describe an outline which curves outward. Synonymous with excurvate and the opposite of concave. Suggested that this term only be used to describe basal edges.
  17. any line drawn through the polygon (and not tangent to an edge or corner) meets its boundary exactly twice.
  18. Curved upwards, when seen from the top of the pan.
  19. Curved, as in the shape of the outside of a circle. Usually referring to the price/required yield relationship for option-free bonds.
  20. AN OPTICAL LENS FORM HAVING BOTH LENS SURFACES CURVED OUTWARDS
  21. A lens which is thicker in the centre than at the edge (converging lens) is known as a convex lens. Convex spectacle lenses (plus lenses) are used for far sightedness and age-related presbyobia.
  22. Said of a new camshaft lifter. The lifter bottom is rounded with the lowest point occurring near the center, so it will contact the camshaft lobe somewhere near its center, rather than wearing the edges.
  23. a polyhedron in which all the flat surfaces slope outwards
  24. A polygon whose all angles are less than the straight angle (180^°).
  25. of a surface, curving outward, or toward the eye. For example, the outer surface of a ball appears convex. In geometry, the term is used to describe any polygon possessing no interior angle greater than 180°. Convex is the opposite of concave.
