A tangent
A tangent at that point where a straight line just touches a curve and a secant line when the straight line bisects the curve.
In geometry a straight line that touches a curve is called a tangent.
curve surface area
It is a straight line that touches the curve such that the line is perpendicular to the radius of the curve at the point of contact.

A tangent is a line which touches, but does not cross, a curved line.
A curved line is a line that is not straight.

With a curved path you have to slow down to curve as with a straight path you dont have to slow down you can do as fast as you need to go to get threw it.
convex
A curved surface is like imagining a sheet of paper that is bent or a flag waving in the wind. A curved edge is like an elastic stick bent in one(C curve) or more points(S curve). The curved surface beeing 3 dimensional(3D) and the curved edge 2 dimensional(2D) unlike the simple surface and edge which are 2D respectively 1D.
The meniscus - the upward curve of a liquid in a narrow vessel.
