Answer 1

It's ASA, it tells you that two angles are congruent & you know they share a side when they're stuck together.

Question: Are these triangles or angles or some other figure: "ABD is congruent too CDB and DBC is congruent too BDA."

Answer 3

Click on the picture :p

Answer 4

@Toristar9504 --> I have viewed the figure but I see triangle ABD, triangle CDB, as well as Angle ABD and Angle CDB. Three points do not automatically indicate a triangle or an angle.

Answer 5

Yeah, it could also be CPCTC. I assumed they were angles.
