Imagine a circle, center at O, and the endpoints of the chord are on the circle at points A and B. A segment extends from point O and is perpendicular to the chord segment AB. Call this intersection point, which is also a perpendicular bisector, point P.\r

\n" ); document.write( "\n" ); document.write( "That description is of two right triangles sharing a side, OP. These values are known:
\n" ); document.write( "OP = 3;
\n" ); document.write( "OA = OB = 5.
\n" ); document.write( "You want to find values for AP or BP, and knowing just one of them, you know that AB=2AP=2BP.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Pythagorean Right Triangle Equation will let you solve for AP or BP.

\n" ); document.write( "\"9%2BAP%5E2=25\"
\n" ); document.write( "\"AP%5E2=16\"
\n" ); document.write( "\"highlight%28AP=BP=4%29\"
\n" ); document.write( "The chord described, which is AB, is \"highlight%28AP%2BBP=4%2B4=8%29\"
\n" ); document.write( "
