In triangle `A B C ,R(b+c)=asqrt(b c),w h e r eR` is the circumradius of the triangle. Then the triangle is a)isosceles but not right b)right but not isosceles c)right isosceles d)equilateral

In triangle ABC,R(b+c)=a sqrt(bc), whereR is the circumradius of the triangle.Then the triangle is a)isosceles but not right bright but not isosceles c)right isosceles dequilateral

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

In a triangle A B C\ a : b : c=sqrt(3)\ :1\ :\ 1, then the triangle is- right angled triangle (b) abtuse angled triangle acute angled triangle, which is not isosceles Equilateral triangle

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

A triangle with vertices (4,0),(-1,-1), (3,5) is (A) an isosceles and right angled (B) an isosceles but not right angled (C) a right angled but not isosceles (D) neither right angled nor isosceles

The median of a triangle divides it into two (a)congruent triangle (b) isosceles triangles (c)right triangles (d) triangles of equal areas

If sinA=sin^2Ba n d2cos^2A=3cos^2B then the triangle A B C is right angled (b) obtuse angled (c)isosceles (d) equilateral

If sinA=sin^2Ba n d2cos^2A=3cos^2B then the triangle A B C is right angled (b) obtuse angled (c)isosceles (d) equilateral

If sinA=sin^2Ba n d2cos^2A=3cos^2B then the triangle A B C is right angled (b) obtuse angled (c)isosceles (d) equilateral

If one angle of a triangle is equal to the sum of the other two angles,then the triangle is an isosceles triangle (b) an obtuse triangle an equilateral triangle (d) a right triangle
