Let a & b be the length of the 2 sides of a triangle & c the hypotenuse.
\n" ); document.write( "Assume a=3 & b=4 solve for c.
\n" ); document.write( "a^2+b^2=c^2
\n" ); document.write( "3^2+4^2=c^2
\n" ); document.write( "9+16=c^2
\n" ); document.write( "25=c^2
\n" ); document.write( "c=sqrt25
\n" ); document.write( "c=5 ans. for the length of the hypotenuse.
\n" ); document.write( "-----------------------------------------------
\n" ); document.write( "Let a=5 & c=13 solve for b.
\n" ); document.write( "5^2+b^2=13^2
\n" ); document.write( "25+b^2=169
\n" ); document.write( "b^2=169-144
\n" ); document.write( "b^2=25
\n" ); document.write( "b=sqrt25
\n" ); document.write( "b=5 ans. for the other side.
\n" ); document.write( "
