The three methods of relative aging of rocks from your list are:

1. **Cross-cutting relationships** - determining the age of a rock layer by looking at how it is affected by other geological features that cut through it.
2. **Superposition** - the principle that in any undeformed sequence of sedimentary rocks, the oldest layers are at the bottom, and the younger ones are at the top.
3. **Original horizontality** - the principle that sedimentary rocks are deposited in horizontal layers.

"Angular relationships" and "radiometric dating" do not fit the category of relative dating; radiometric dating is a method of absolute dating, and angular relationships is not a standard method for determining relative age.

Thus, the correct answers are:
- Cross-cutting relationships
- Superposition
- Original horizontality
