The figure below shows rectangle abcd with diagonals ac and db:
jimmy wrote the following proof to show that the diagonals of rectangle abcd are congruent:
jimmy's proof:
statement 1: rectangle abcd is given
statement 2: ab - dc because opposite sides of a rectangle are congruent
statement 3: angles abc and dcb are both right angles by definition of a rectangle
statement 4: angles abc and dcb are congruent because all right angles are congruent)
statement 5:
statement 6: triangles abc and dcb are congruent by sas
statement 7: ac - db by cpctc
which statement below completes jimmy's proof?
ad - ad (reflexive property of congruence)
ad - ad (transitive property of congruence)
obc - bc (reflexive property of congruence)
bc - bc (transitive property of congruence)
