If sides of triangle `A B C` are `a , ba n dc` such that `2b=a+c` then `b/c >2/3` (b) `b/c >1/3` `b/c<2` (d) `b/c<3/2`

If sides of triangle ABC are a,b and c such that 2b=a+c then (b)/(c)>(2)/(3)( b) (b)/(c)>(1)/(3)(b)/(c)<2 (d) (b)/(c)<(3)/(2)

If side of triangles are b-2a+2c , a+3b-3c and 2a-b+c , then find the perimeter .

If D is the mid-point of the side B C of triangle A B C and A D is perpendicular to A C , then 3b^2=a^2-c ^2 (b) 3a^2=b^2 3c^2 b^2=a^2-c^2 (d) a^2+b^2=5c^2
