To test if a triangle is right, you should use the Pythagorean Theorem.
\n" ); document.write( " $\"a%5E2%2Bb%5E2=c%5E2\"$
\n" ); document.write( "Because the sides 47 and 66 are shorter, they are the legs.
\n" ); document.write( " $\"47%5E2%2B66%5E2=c%5E2\"$
\n" ); document.write( "Because 89 is the longest, it is the hypotenuse.
\n" ); document.write( " $\"47%5E2%2B66%5E2=89%5E2\"$
\n" ); document.write( "Next, find the squares
\n" ); document.write( " $\"2209%2B4356=7921\"$
\n" ); document.write( "Add the numbers together
\n" ); document.write( " $\"6565=7921\"$
\n" ); document.write( "

Because the numbers don't fit in the pythagorean theorem, the triangle is not right. \n" ); document.write( "
