If a cos A=b cos B , then the triangle ,is

If a cos B = b cos A then the triangle is

In a triangle ABC, if a cos A=b cos B, show that the triangle is either isosceles or right angled.

If a cos A = b cos B then triangle ABC is

In a Delta ABC with usual notations, if (a)/(cos A)=(b)/(cos B)=(c )/(cos C) , then the triangle is :

Which of the following statements is true I : In a DeltaABC if a= R tan A then b^(2)+c^(2)=bc+a^(2) II. In a DeltaABC if a sin A= c cos B+ b cos C then the triangle is right angled

If in a triangle, a/(cosA)= b/(cos B) =c/(cos C) , then the triangle is :

In a triangle ABC ,cos A + cos B + cos C = 3/2 , then the triangle ,is

In Delta ABC, if cos A+cos B+ cos C=3//2 , then the triangle is
