You can put this solution on YOUR website!
the dashed line forms two congruent right triangles; with a hypotenuse of 20 and one side of 12\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can find the dashed side using the Pythagorean Theorem
\n" ); document.write( "or
\n" ); document.write( "recognize a Pythagorean Triple, 3-4-5 (or in this case 12-16-20)
\n" ); document.write( "
