triangle ABC using (=) to mean congruent\r
\n" ); document.write( "\n" ); document.write( "1.angle A(=)angle B(=)angle C...........1. given\r
\n" ); document.write( "\n" ); document.write( "2 if angle A(=)angle B then AC(=)BC.....2. converse of base angle theorem
\n" ); document.write( " if angle B(=)angle C then AC(=)AB
\n" ); document.write( "3. since AC(=)BC and AC(=)AB............3. transitive
\n" ); document.write( " then BC(=)AB
\n" ); document.write( "4. All sides are equal.therefore......... 4. definition of an equilateral tri
\n" ); document.write( " this is an equilateral triangle.
