You can put this solution on YOUR website!
a) equilateral
\n" ); document.write( "say each side is x, so when you follow the formula you will get a=b=c=x
\n" ); document.write( "\"x%5E2%2Bx%5E2%2Bx%5E2=x%5E2%2Bx%5E2%2Bx%5E2\"
\n" ); document.write( "\"3x%5E2=3x%5E2\" so they are equal
\n" ); document.write( "
\n" );
