Will give brainliest and if you have proofthe figure below shows a rectangle abcd having diagonals ac and db: a rectangle abcd is shown with diagonals ac and bd. zinnia wrote the following proof to show that the diagonals of rectangle abcd are congruent: zinnia's proof: statement 1: in triangle adc and bcd, ad = bc (opposite sides of a rectangle are congruent) statement 2: angle adc = angle bcd (angles of a rectangle are 90°) statement 3: dc = dc (reflexive property of equality) statement 4: statement 5: ac = bd (by cpctc) which statement below completes zinnia's proof? triangle adc and bcd are congruent (by asa postulate) triangle adc and bcd are congruent (by sas postulate) triangle adc and cba are congruent (by asa postulate) triangle adc and cba are congruent (by sas postulate)
