arc
If the curve is part of the circumference of the circle, it is called an arc.
A circle *encloses* an area, and the "area of a circle" is the area it encloses, πr^2. A circle is a 1-dimensional curved line; it is a set of points equidistant from a given point (the center), with that distance being the radius of the circle. This means the inside of the circle is not part of the circle (it's called a disk if you include the inside points).To find the area, multiply pi (π) by the radius squared (r^2), so you get πr^2.Yes, it does.
segment
It is a Line Segment.
No, only at one point, perpendicular to the radius

segment
The shortest route between two points on the surface of a planet, when routes are limited to the planet's surface, is the arc of the great circle that connects the two points. The shortest route between two points anywhere, without regard to intervening matter or energy preventing the route from being followed, is always the line connecting the two points.
Two points do not provide enough information to define a circle: a minimum of three points is required to uniquely define a circle unless one of the points happens to be the centre and the other is on the circle. In that case, however, it is necessary to know which is which.
Okay if your talking about a circle with a line through it and has 2 end points on the circle, it would be called a chord and if it crosses the center it's called a diameter.
It is a Line Segment.
No, only at one point, perpendicular to the radius
circle has single center point and is equidistant to point of radius,while oval has four(4) center points with two(2) different radius.
A chord
A line can be tangent to a circle in which case it intersects it in one point, it can intersect it in two points, or no points at all. So the choices are 0,1 or 2.
