1. the diagonals of a parallelogram bisect each other.
2. the opposite sides of a parallelogram are congruent.
3. the opposite sides of a parallelogram are congruent and are parallel to each other.
4. the opposite angles of a parallelogram are congruent.
5. the diagonals of a parallelogram bisect each other; line ML bisects line SI into 2 equal parts. therefore, line SE is half the measure of line SI: line SI = line SE + line IE
the diagonals of a parallelogram bisect each other; line SI bisects line LM into 2 equal parts. therefore, line EM is congruent to line EL.
