Let me provide a different way of looking at it. It may be simpler to see your question with regard to \$R_1\$ and \$R_2\$ using math.Let's keep the BJT base current in place and assume that it is some...

BJT four-resistor bias circuit analysis, parallel resistors
I don't understand why R1 and R2 are in parallel.I need to find the Thévenin resistance of the circuit, and my textbook says that R1 and R2 are in parallel, but I don't understand why.I really struggle...
