Circular arc

A circular arc is the <a href="/facts/Arc_(geometry)/xBQ0pTBW">arc</a> of a <a href="/facts/Circle/9fy5ggKn">circle</a> between a pair of distinct <a href="/facts/Point_(geometry)/6YPAvX2a">points</a>. If the two points are not directly opposite each other, one of these arcs, the minor arc, <a href="/facts/Subtended_angle/GQxln7lP">subtends</a> an angle at the center of the circle that is less than <a href="/facts/Pi/vC0UBj1q">π</a> <a href="/facts/Radian/Srd38Sxa">radians</a> (180 <a href="/facts/Degree_(angle)/f48Ns8SX">degrees</a>); and the other arc, the major arc, subtends an <a href="/facts/Angle/gFUTEQYq">angle</a> greater than π radians. The arc of a circle is defined as the part or segment of the <a href="/facts/Circumference/r1rntU0f">circumference</a> of a circle. A straight line that connects the two ends of the arc is known as a <a href="/facts/Chord_(geometry)/aAyoEdLd">chord</a> of a circle. If the <a href="/facts/Length/EwFyAqGH">length</a> of an arc is exactly half of the circle, it is known as a <a href="/facts/Semicircle/Im66xpfu">semicircular arc</a>.
