That is called an arc.
Not at all! The circumference is the length of the boundary of a circle. A chord is a straight line(or a line segment) that passes through two points on the boundary of a circle (or on a curve).
An arc is part of the circumference of a circle
The boundary which defines the area of a circle is known as the circumference of the circle.However if one wants to be precise, the circumference is the distance around the outside of the circle, not the circle itself. The term "circle" itself means the boundary. It has an interior and an exterior.A circle can be defined as all the points that are the same distance from a given point.
The diameter of a circle is the length of a line passing through the center of a circle that connects two points on the circumference. The circumference is the distance around the edge of a circle.
An arc is part of the circumference of a circle
well its true that every chord contains two points of the circumference of a circle 'cos a chord is the straight line between two points on the circumference
It is a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).
An arc (circumference only), or a segment.
If the curve is part of the circumference of the circle, it is called an arc.
There are an infinite number of points on the circumference of a circle and an infinite number of points on a semi-circle so the answer to your question is "An infinite number of pairs of points."
Yes, and the two points are located on the circumference of the circle
circumference * * * * * A circumference has no end-points! One possible answer is a chord.
