Fill int the blanks choosing correct answer from the bracket. In triangle ABC if cosA/a = cosB/b = cosC/c then the triangle is _____.

In Delta ABC prove that a(cosB + cosC) = 2(b+c) sin^2(A/2)

In DeltaABC,a/cosA=b/cosB=c/cosC,ifb=2 then the area of the triangle is

In a triangle ABC with fixed base BC, the vertex A moves such that cos B+cosC=4sin^(2)A/2 . If a,b,c denote the lengths of the triangle opposite to the angles A,B and C respectively, then

If in triangle ABC cosA+cosB+cosC=3/2 then prove that triangle is equilateral

In Delta ABC If: 2(cosA)/a + (cos B)/(b) + 2(cosC)/(c) = a/(bc) + b/(ca) , then: /_A =

In any triangle ABC, if cosA + cos B + cosC =3/2 , then show that the triangle is equilateral.
