Charlotte and Hillary decide to share a grilled cheese sandwich. Hillary does not believe the two
pieces of sandwich are the same size. Charlotte explains that together the sandwich makes a
rectangle. This means that m ZA = m ZC = 90° and ZA =ZC. Knowing that BC || AD, the
transversal is BD. So, ZADB=ZCBD because they are alternate interior angles.
B
What additional information can Charlotte
use in order to prove that the two pieces of
the sandwich are congruent using AAS
Postulate?
BD= BD using the Reflexive Property.
AD= BC by the Perpendicular Line
Postulate
Charlotte does not need any additional
information. She has already proved
AABD=ACBD using the AAS
BA= CD by the Parallel Line
Postulate.
