Isosceles! If right triangle has a 45 degree angle, then the other angle not 90 degrees is also 45 degrees. Two sides are equal, too. This triangle is half a square.\r

\n" ); document.write( "\n" ); document.write( "Let s be length of the legs and let h be the hypotenuse.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Area, A=(1/2)s^2, meaning \"s=sqrt%282%2AA%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The two length s meet at the right-angle.
\n" ); document.write( "\"h%5E2=s%5E2%2Bs%5E2\", ... and you do the steps,... \"h=s%2Asqrt%282%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Perimeter is the sum of the lengths that make the triangle.
\n" ); document.write( "Perimeter is \"s%2Bs%2Bh\"
\n" ); document.write( "\"perimeter=2%2Asqrt%282%2AA%29%2Bs%2Asqrt%282%29\"
