Schwarz reflection principle

Schwarz Reflection Principle is like a game between two people. It's a way for two people to figure out the truth. One person starts by saying something. The other person then reflects what was said back to the first person. The first person then decides whether it is true or false. If it is true, then the first person says "yes" and the game ends. If it is false, then the first person says "no" and the game keeps going until the two people can figure out the truth. It's like a back and forth conversation!
