An arc (circumference only), or a segment.
arc
An arc is part of the circumference of a circle
a chord.
If the curve is part of the circumference of the circle, it is called an arc.
an arc
An unbroken part of a circle consisting of two endpoints on the circle and all the points between them is called a "chord." The chord connects the two endpoints, and the arc formed by the endpoints on the circle is the corresponding arc of the chord. Together, they define a segment of the circle's circumference.
An arc.
A segment between two points on a circle is
A part of a circle between two points on a circle is called is called an arc.
The portion of a line that falls between two points is called a line segment.
It could be an arc (a curved portion of the circumference), a chord (the straight line distance between two points) , or a wedge (the plane area bounded by two radii and an arc).Remember the circle is a plane figure, not the curved line we draw. " A circle is bounded ... ."
arc
In geometry, an arc is a curved portion of a circle. It is defined by two endpoints and the points along the circumference of the circle that lie between the endpoints. The measure of an arc is typically given in degrees.
It would be call the 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."
An arc is part of the circumference of a circle
In geometry, a chord is a line segment that connects two points on a circle. If a chord intersects a circle at exactly 7 points, it means the chord passes through the circle and touches it at 7 different points. This relationship between a triangle, a circle, and a chord with 7 points of intersection is a geometric concept that demonstrates the properties of circles and their chords.
