In a `Delta`ABC, if
(i)sin `(A)/(2) sin"" (B)/(2) sin"" (C )/(2) gt 0` (ii)sin`AsinBsinC gt 0`

In a Delta ABC, prove that a sin ((A)/(2) + B) = (b + c) sin ""(A)/(2)

Delta ABC,abc sin((A)/(2))sin((B)/(2))sin((C)/(2))=

In a Delta ABC if a^(2)sin(B-C)+b^(2)sin(C-A)+c^(2)sin(A-B)=0, then triangle is

In Delta ABC, if a,b,c are in A.P.then (2sin((A)/(2))sin((C)/(2)))/(sin((B)/(2)))=

In a triangle ABC, prove that :a sin((A)/(2)+B)=(b+c)sin((A)/(2))

In a Delta ABC " if " a^(2) sin (B - C) + b^(2) sin (C - A) + c^(2) sin (A - B) = 0 , then triangle is

In Delta ABC, prove that (a^(2)sin (B-C))/(sin A) + (b^(2) sin (C-A))/(sin B) + (c^(2) sin (A-B))/(sin C) = 0

In a Delta ABC,(sin A)/(sin C)=(sin(A-B))/(sin(B-C)), then a^(2),b^(2),c^(2) are in
