we can use principals from geometry to find the lengths of segments inside circles.  before we begin, we will state a few theorems. solution:  we see that x is the leg of a right triangle formed by portions of the diameter, radius, and a chord in the circle.  since the other leg (9.6) and the hypotenuse (15.6) are known, we can use the pythagorean theorem to find x.  we have \({9.6^2} + {x^2} = {15.5^2}\) \(92.16 + {x^2} = 240.25\) \({x^2} = 148.09\) \(x = 12.2\), rounded to the nearest tenth   solution:  in the picture above, we see that a radius of the circle (and thus the diameter) is parallel to the chord containing the value 15 as one of its segments.  then, by our second theorem above, the diameter bisects the sword, so that the values of the segments on each side of the diameter are equal.  that is, the value of both segments of the chord are 15.  thus we have obtained a right triangle with two known legs(6 and 15) and the hypotenuse, x, is the desired value.  we use the pythagorean theorem:

in circle a, chord bc cuts off two arcs, bc and bdc. we say the minor arc, bc, example 2: find eb. enter the height and width (chord) above to draw the arc template. an arc with radius 150 and chord length (arc width) of for example, the major arc associated with ™apb above is acb . egf below is a semicircle. measuring arcs the is , arcs and chords worksheet, arcs and chords worksheet, printable arc template, arcs and chords worksheet 10-3, lesson 12-2 practice a arcs and chords answers.
