if one leg ( $\"a\"$ ) in a 45°-45° right triangle has a length of $\"8\"$ , than the other leg ( $\"b\"$ ) has a length of $\"8\"$ too because it’s an isosceles triangle (both legs have the same length)\r
\n" ); document.write( "\n" ); document.write( "so, the length of a hypotenuse $\"c\"$ is:\r
\n" ); document.write( "\n" ); document.write( " $\"c%5E2=a%5E2%2Bb%5E2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"c%5E2=8%5E2%2B8%5E2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"c%5E2=64%2B64\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"c%5E2=2%2A64\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"c=sqrt%282%2A64%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"c=8%2Asqrt%282%29\"$ =>the length of a hypotenuse\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
