Answer:
2. I am pretty sure that it is right angles are congruent.
4. Angle O and R are congruent, never heard of their angles theorem but I think it might be related to CPCTC.
Step-by-step explanation:
Well a square is always used to represent a right angle so and both angle Q and N have squares and that should mean that they are both 90 degrees. Also while vertical angels are congruent, angles Q and N are not vertical from each other, Reflexive Property is if it is a side and not an angle I think.
