If a,b and c are the sides of a traiangle such that `b.c =lamda ^(2),` then the relation is `a, lamdaand A` is

If a,b and c arethe sides of a traiangle such that b.c =lamda ^(2), then the relation is a, lamdaand A is

If a, b, c denote the sides of a DeltaABC such that a^(2)+b^(2)-ab=c^(2) , then

If a,b,c are the sides of a triangle then a/(b+c-1)+b/(c+a-b)+c/(a+b-c)=

If sides of triangle ABC are a, b, and c such that 2b = a + c , then

Let a,b,c be the sides of a triangle ABC, a=2c,cos(A-C)+cos B=1. then the value of C is

If a, b, c are sides of a triangle, then ((a+b+c)^(2))/(ab+bc+ca) always belongs to

If a, b, c are sides of a triangle, then ((a+b+c)^(2))/(ab+bc+ca) always belongs to

If a,b and c are sides of a ritht triangle where c is the hypotenuse, prove that the radius of the circle which touches the sides of the triangle is r = (a + b-c)/(2).

Given that a , b , c , are the side of a A B C which is right angled at C , then the minimum value of (c/a+c/b)^2 is

If a , b , c are the sides of triangle , then the least value of (a)/(c+a-b)+(b)/(a+b-c)+(c )/(b+c-a) is
