In a triangle `A B C ,` if `acosA=bcosB ,` show that the triangle is either isosceles or right angled.

If acosA=bcosB , then either the triangle is isosceles or right angled.

In a triangle A B C , if cos A=(sinB)/(2sinC) , show that the triangle is isosceles.

If a cosA=b cos B , then prove that either the triangle is isosceles or right triangle.

In triangle ABC , if cosA+sinA-(2)/(cosB+sinB)=0 then prove that triangle is isosceles right angled.

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

In any triangle ABC, if (cos A + 2 cos C)/(cos A + 2 cos B) = (sin B)/(sin C) then prove that, the triangle is either isosceles or right angled.

In DeltaABC, (b^(2)+c^(2))sin(B-C)=(b^(2)-c^(2))sin(B+C) , then prove that the triangle in either isosceles or right angled.

In a Delta A B C ,\ ifsin^2A+sin^2B=sin^2C , show that the triangle is right angled.

If in a Delta A B C ,cos^2A+cos^2B+cos^2C=1, prove that the triangle is right angled.

If the bisector of the vertical angle of a triangle bisects the base of the triangle. then the triangle is isosceles. GIVEN : triangle A B C in which A D is the bisector of angle A meeting B C in D such that B D=DC TO PROVE : triangleA B C is an isosceles triangle.
