A secant line touches a circle at two points. On the other hand a tangent line meets a circle at one point.

No, lines do not have endpoints, because they continue on forever in two directions, and never stop at an endpoint.

Two lines tangent to a circle at the endpoints of its diameter are parallel. See related link for proof.

A tangent of a circle is not a secant of a circle, so the answer is false. A tangent of a circle is a line that intersects the curve of the circle at exactly one point on the curve. It could be said to "touch" the circle at one unique location. Obviously there are an infinite number of lines that can be drawn to do this. A secant of a circle is a line that touches the curve of the circle at exactly two unique points on the curve. It might be considered "similar" to the chord of a circle, which is a line segment with endpoints at two unique locations on the curve of a circle. Except that the secant of a circle is a line and not a line segment. Any chord of a circle that is overlaid with a line, which is like saying that we "extend" the line segment that is the chord of the circle on each end, and do so all the way to infinity, we'll have the secant of a circle. Let's take things one step further. If a circle and a line are coplanar (lie in the same plane), one of three things will be true. Either they will have no (zero) points of intersection, or they'll have one point of intersection, or they'll have two points of intersection. There are no other possibilities. Think this through and it will make complete sense. A lot of geometry will "work like this" when we study it and think it through. Use the links below to check out the idea of a tangent and a secant of a circle.
A line segment has two endpoints. Lines are infinite, so they have no endpoints; while rays start at one point and continue infinitely; and line segments are completely finite, so they have endpoints at both ends.

A plane is made up of an infinite number of sides (lines) that are joined at endpoints. This creates a flat surface that extends infinitely in all directions. Each side of a plane is defined by two points.
