Zinnia wrote the following proof to show that the diagonals of rectangle ABCD are congruent: Zinnia's proof
Statement 1: Rectangle ABCD is given
Statement 2. AD BC because opposite sides of a rectangle are congruent
Statement 3 DC DC by the reflexive property of congruence
Statement 4: Angles ADC and BCD are both right angles by definition of a rectangle
Statement 5 Angles ADC and BCD are congruent because all right angles are congruent
Statement 6
Statement 7 AC BD by CPCTC
Which statement below completes Zinnia's proof?
O Triangles ADC and BCD are congruent (by ASA postulate)
Triangles ADC and BCD are congruent (by SAS postulate)
Triangles ADC and CBA are congruent (by ASA postulate)
Triangles ADC and CBA are congruent (by SAS postulate)
