whenever we see a triangle type of connection b/w the resistors we can always transform that to star form......just by a simple calculation...

$R_a = rac{R_mathrm{ac}R_mathrm{ab}}{R_mathrm{ac} + R_mathrm{ab} + R_mathrm{bc}}$

$R_b = rac{R_mathrm{ab}R_mathrm{bc}}{R_mathrm{ac} + R_mathrm{ab} + R_mathrm{bc}}$

$R_c = rac{R_mathrm{bc}R_mathrm{ac}}{R_mathrm{ac} + R_mathrm{ab} + R_mathrm{bc}}$
click on the diagram below to see the image clearly....it was not uploaded properly......rate me if useful
