That would be the flaps. There are flaps on the trailing edge of a wing on most aircraft and there can also be leading edge flaps as well, often seen on the big airliners. These flaps will be lowered and will effectively increase the curvature of the wing, allowing it fly at higher angles of attack for greater lift. It also produces greater drag, useful for dropping altitude without speeding up and flying slow on approach to landing.
Lordosis is a spinal curvature in the median plane with an posterior concavity.
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
By increasing its radius of curvature to infinity.
Plane mirrors don't have one, I'd say it was 0.

Not necessarily. A plane dissecting a sphere would create a circle in that plane. so in order for the "line" to be both on the plane and the sphere the line would have to be a curve or segment of a circle.
"blank on" = greater convex curvature on the upper surface of
DIP
Not sure about a name, but "an infinite surface with zero curvature" is an equivalent phrase.
An infinite flat surface, or an infinite surface with zero curvature.

To create a plane, infinitely many. To uniquely determine a plane, just three.
