WebA chord is a line segment whose endpoints lie on the circumference of a circle. A tangent is a line that touches a circle at exactly one point. This is called the point of tangency. An arc is a section of the circumference of a circle. A sector is a part of the interior of a circle, bounded by an arc and two radii. Webvideo explaining the proof of the tan chord theorem
