Let’s start with the circle with centre C. The line AB is a chord and CE is a radius. The lines CE and AB intersect at the point D at 90 degrees to one another because they are perpendicular. 2. We then draw the lines AC and BC. The length AC = BC as they are both radii of the circle. Chords were used extensively in the early development of trigonometry. The first known trigonometric table, compiled by Hipparchus, tabulated the value of the chord function for every 7+1/2 degrees. In the second century AD, Ptolemy of Alexandria compiled a more extensive table of chords in his book on astronomy, giving the value of the chord for angles ranging from 1/2 to 180 degrees by in… early cretaceous

WebApply chord theorems. Arcs determined by angles whose vertex is the center of a circle and chords (segments that connect two points on a circle). The intersecting chords theorem or just the chord theorem is a statement in elementary geometry that describes a relation of the four line segments created by two intersecting chords within a circle. It states that the products of the lengths of the line segments on each chord are equal. It is Proposition 35 of Book 3 of Euclid's Elements. cst atg5WebTheorem 1. PARGRAPH When two chords of the same circle intersect, each chord is divided into two segments by the other chord.
