Which theorem or postulate can be used to show ABC CDA?

We refer to this as the Side Side Side Postulate or SSS. And as seen in the image to the right, we show that trianlge ABC is congruent to triangle CDA by the Side-Side-Side Postulate.

What theorem determines that ABC and CDA are congruent?

First show that ABC ≡ CDA using the SSS congruence test.
Hence	ACB = CAD and CAB = ACD	(matching angles of congruent triangles)
so	AD \|\| BC and AB \|\| DC	(alternate angles are equal.)

Which similarity postulate or theorem can be used to determine that ABC is similar to DBE?

If so, which postulate or theorem proves these two triangles are similar? △DBE is similar to △ABC by the SAS Similarity Theorem .

Is triangle ABC congruent to Triangle DCB Why?

1 Expert Answer Hi Sarah, you can use the side, angle, side theorem to prove that triangle ABC is congruent to triangle DCB. Side 2: CB is congruent to CB, reflex property of congruent lines.
