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

If a,b,c are sides of Delta ABC are in A.P.then

If a,b,c are the sides of a triangle and s=(a+b+c)/(2), then prove that 8(s-a)(s-b)(s-c)<=abc

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

If the sides a,b and c of a triangle ABC are in A.P.then (b)/(c) belongs to

Let the incircle of a Delta ABC touches sides BC, CA and AB at D,E and F, respectively. Let area of Delta ABC be Delta and thatof DEF be Delta' . If a, b and c are side of Detla ABC , then the value of abc(a+b+c)(Delta')/(Delta^(3)) is (a) 1 (b) 2 (c) 3 (d) 4

If a, b, c are the sides of the triangle ABC such that a^(4) +b^(4) +c^(4)=2c^(2) (a^(2)+b^(2)), then the angle opposite to the side c is-

If a, b, c are the sides of the triangle ABC such that a^(4) +b^(4) +c^(4)=2x^(2) (a^(2)+b^(2)), then the angle opposite to the side c is-
