`DeltaABC` has different side lengths a,b,c. If `a^(2),b^(2),c^(2)` as sides form another `DeltaPQR`, then `DeltaABC` will always be

If cot ""A/2 =(b+c)/(a), then DeltaABC is

If cot ""A/2 =(b+c)/(a), then DeltaABC is

If cot ""A/2 =(b+c)/(a), then DeltaABC is

In a DeltaABC," if " a^(2)sinB=b^(2)+c^(2) , then :

In a DeltaABC," if " a^(2)sinB=b^(2)+c^(2) , then :

In a DeltaABC," if " a^(2)sinB=b^(2)+c^(2) , then :

If the sine of the angles of DeltaABC satisfy the equation c^(3)x^(3)-c^(2) (a+b+c)x^(2)+lx +m=0 (where a,b,c are the sides of DeltaABC), then DeltaABC is
