Use the Pythagorean theorum to solve this:
\n" ); document.write( "\"a%5E2%2Bb%5E2=c%5E2\"
\n" ); document.write( "Where a and b are the sides, and c is the hypotenuse.
\n" ); document.write( "---------------------
\n" ); document.write( "\"3%5E2%2Bb%5E2=5%5E2\"
\n" ); document.write( "\"9%2Bb%5E2=25\"
\n" ); document.write( "\"b%5E2=16\"
\n" ); document.write( "\"highlight%28b=4%29\"
\n" ); document.write( "---------------------
\n" ); document.write( "Note this is what is called a 3-4-5 right triangle. This rule applies to all similar triangles to the 3-4-5, so you can solve for the sides of this kind of triangle easily. For example, if you are given a=6, b=8, you automatically know that c=10, since this is a \"3-4-5 times 2.\"
