The three correct methods of relative aging of rocks from your list are:
-
Superposition - The principle that in undisturbed sedimentary layers, the oldest layers are at the bottom and the youngest are at the top.
-
Original Horizontality - The principle that layers of sediments are originally deposited horizontally under the action of gravity.
-
Cross-Cutting Relationships - The principle that if a geological feature cuts through another feature, the feature that has been cut is older.
Radiometric dating is a method of absolute dating, while original angularity and angular relationships are not standard methods used for relative dating in geology.
