Practice problems of the chord - page 3 of 4
A chord of a circle is a straight line segment whose endpoints both lie on the circle. A chord that passes through a circle's center point is the circle's diameter. The word chord is from the Latin chorda meaning bowstring.Direction: Solve each problem carefully and show your solution in each item.
