The lengths of the sides of the right triangle with 45degree angles and a hypotenuse of 6 is
\n" ); document.write( "\"36+=+a%5E2+%2B+a%5E2\" Both sides are the same length
\n" ); document.write( "\"36+=+2a%5E2\"
\n" ); document.write( "\"18+=+a%5E2\"
\n" ); document.write( "\"3sqrt%282%29+=+a\"
\n" ); document.write( "So the perimeter is \"6+%2B+3%2Asqrt%282%29+%2B+3%2Asqrt%282%29\"
\n" ); document.write( "Answer D\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2) Any triangle with sides in the ratio of 3:4:5 is a right triangle.
\n" ); document.write( "So 12:16:20 is a right triangle. A right triangle is not obtuse.
