WebAn angle formed by a chord ( link) and a tangent ( link) that intersect on a circle is half the measure of the intercepted arc . x = 1 2 ⋅ m A B C ⏜ Note: Like inscribed angles, when the vertex is on the circle itself, the angle … 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…
