let side of triangle be a\r
\n" ); document.write( "\n" ); document.write( " The altitudes, medians and the bisectors of a equilateral triangle are equal to 1/2a√3
\n" ); document.write( "Area = 1/2 * base * altitude\r
\n" ); document.write( "\n" ); document.write( "area = \"%281%2F2%29+%2A+a+%2A+%281%2F2+%2A+a%2A+sqrt%283%29%29\"\r
\n" ); document.write( "\n" ); document.write( "area = \"%281%2F4%29%2Aa%5E2sqrt%283%29\"\r
\n" ); document.write( "\n" ); document.write( "perimeter = 3a\r
\n" ); document.write( "\n" ); document.write( "\"3a=+%281%2F4%29+a%5E2sqrt%283%29\"
