Resistances Series and parallel

Help

@pankaj497 help guyzz


@amitkumarbaghel SIR why there is no resistance between EC and FD Please Explain.

@pankaj497 Since the circuit is symmetrical about CD line, therefore the current in the AC and CH branch will be same , similarly the current in the BE and EG branch is same.
From which we can apparently conclude that there will be no current through branch CE i.e. C and E are equipotential points so that can be removed from circuit.
we can repeat similar process for removing branch FD.
hope you get the answer.
