The figure below shows a quadrilateral abcd. sides ab and dc are congruent and parallel a quadrilateral abcd is shown with the opposite sides ab and dc shown parallel and equal a student wrote the following sentences to prove that quadrilateral abcd is a parallelogram: side ab is parallel to side dc so the alternate interior angles, angle abd and angle cdb, are congruent. side ab is equal to side dc and db is the side common to triangles abd and bcd. therefore, the triangles abd and cdb are congruent by sss postulate. by cpctc, angles dbc and bda are congruent and sides ad and bc are congruent. angle dbc and angle bda form a pair of alternate interior angles. therefore, ad is congruent and parallel to bc. quadrilateral abcd is a parallelogram because its opposite sides are equal and parallel. which statement best describes a flaw in the student's proof? 1.angle dbc and angle adb form a pair of vertical angles which are congruent. 2.triangles abd and cdb are congruent by the sas postulate. 3. triangles abd and bcd are congruent by the aas postulate. 4.angle dbc and angle adb form a pair of corresponding angles which are congruent.
