\n" ); document.write( "

The perpendicular bisector is drawn from the circle's center to the chord, which it bisects
\n" );
document.write( "We now draw 2 radii to each endpoint of the chord
\n" );
document.write( "We now have an isosceles triangle which consists of 2 right triangles, with 2 radii as its hypotenuses. 
\n" );
document.write( "To find the radius, we use the pythagorean theorem, and we get: . This results in a radius value of  \n" );
