`"In a "DeltaABC, if(cosA)/a=(cosB)/b,"show that the triangle is isosceles".`

In any triangle ABC : If (cosA)/a= (cosB)/b , prove that the triangle is isosceles.

If A, B, C are the angles of a triangle ABC and if cosA=(sinB)/(2sinC) , show that the triangle is isosceles.

If in a triangle ABC, (cosA)/a=(cosB)/b=(cosC)/c ,then the triangle is

If in a triangle ABC, (cosA)/a=(cosB)/b=(cosC)/c ,then the triangle is

If in a triangle ABC, (cosA)/a=(cosB)/b=(cosC)/c ,then the triangle is

In a DeltaABC " if " a cosA=bcosB the prove that triangle is either isosceles or right angled .

In /_\ABC ,a/cosA=b/cosB=c/cosC.Show that the triangle is equilateral.

If 2cosA=sinB/sinC then show that the triangle is an isosceles triangle

In DeltaABC, c (a cosB-b cosA)=
