The 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 SAS postulate)

Look at the figure shown below: RQ is a segment on which a perpendicular bisector PS is drawn. S is the midpoint of RQ. Which step should be used to prove that point P is equidistant from points R and Q?

Using SAS postulate, prove that triangles PQS and PRS are congruent.

The figure below shows a parallelogram ABCD. Side AB is parallel to side DC and side AD is parallel to side BC: A quadrilateral ABCD is shown with the two pairs of opposite sides AD and BC and AB and DC marked parallel . The diagonal are labeled BD and AC A student wrote the following sentences to prove that the two pairs of parallel opposite sides of parallelogram ABCD are congruent: For triangles ABD and CDB, alternate interior angles ABD and CDB are congruent because AB and DC are parallel lines. Alternate interior angles ADB and CBD are congruent because AD and BC are parallel lines. DB is congruent to DB by _______________. The triangles ABD and CDB are congruent by ASA postulate. As corresponding parts of congruent triangles are congruent, AB is congruent to DC and AD is congruent to BC by CPCTC. Which phrase best completes the student's proof?
