Question

Theorem: The diagonals of a rectangle are congruent.

Kim is writing the proof of the theorem using two properties of a rectangle as shown below.

• The opposite sides of a rectangle are congruent and parallel.
• Each angle of a rectangle is 90°.



Using the two given properties, Kim can prove that triangle ADB is congruent to triangle BCA using the _________ Postulate.

Answer 1

my best guess is ASA.. since the opposite sides are parallel, alternate interior angles will come into play giving two sets of angles between triangles congruent.. the common side is the that S part of ASA....
so ASA is my guess...:)

Answer 2

Okay, thank you!
