An arc is part of the circumference of a circle
Only round the perimeter of the circle (not across its interior) because a segment is a part of a line or curve between two points.
cicle or semi circle
A circle is a 360º curve. A 25º curve means that the two radius lines which give the start and end of the curve are 25 degrees apart (even if they are not 'visible' in the curve).
A geometrical curve is defined as any set of points. Therefore, counter-intuitively, a straight line is also a geometrical curve.
An arc is part of the circumference of a circle
A straight line that intersects a circle or curve at two points, but which has both end points outside the circle or curve is called a secant. A straight line that links two points on a circle or curve is called a chord. A straight line which touches a circle or curve at one point is called a tangent. A straight line that cuts a circle or curve at one point is a straight line.* For moving diagrams see Related links below this box.

... is called a Great Circle arc.
A chord is a line segment between two points on a given curve. Basically it's two points that are connected with a line which all happens to be on a curve. Most likely a circle
A circle.
A continuous curve surrounding two points will be called an ellipse. Very strictly speaking, the ellipse, circle, etc is the bit inside the curve. e.g. " a circle is bounded by ... "* * * * *Even more strictly speaking, it is any closed curve around two points - it could wobble all over the place.
Only round the perimeter of the circle (not across its interior) because a segment is a part of a line or curve between two points.
A circle is a closed curve where all points are equidistant from a fixed point called the center. It is a two-dimensional shape with no corners or edges.

A line segment with its endpoints on the circumference (curve) of a circle is called a chord of that circle. If it passes through the center of the circle (which it can, but does not have to do), it is called a diameter of the circle. See the links below for more information.Is called a radius.
