\n" ); document.write( "\n" ); document.write( "The perimeter is the easy part, just add the measures of the three sides.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If you divide each of the measures of the sides by 3, you notice that the three sides are in proportion

-- a Pythagorean triple. That means that this is guaranteed to be a right triangle. If you want to confirm that, just calculate

. If the two sides are equal, then you must have a right triangle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In a right triangle, either of the legs can be considered the base of the triangle and the other leg is the height. The area of a triangle is the base times the height divided by 2. So just multiply 9 times 12 and divide by 2 to get the area.\r
