Queries regarding this circuit:

1. I am able to say that this circuit has negative feedback but my procedure is disorganized. I want a step wise procedure to identify the polarity of feedback.
2. In this circuit the 10K resistor is acting as feedback (correct me if I am wrong) but the resistor I am unable to fit the whole thing in format of basic amplifier and feedback amplifier for shunt shunt feedback (again correct if I have wrongly identified the type of feedback topology) I mean the ports of feed back resistor are not lying at end like in below diagram but in some what middle thus how will I do feedback analysis of the circuit?Consider the circuit shown is incremental model of actual circuit where BJT is biased in active region
