If origin is the ortho-center of an equilateral triangle whose vertices are a , b , c then

Options

  1. Aa + b = c
  2. Ba + b =- c
  3. C| a |^2=| b |^2=| c |^2
  4. Da = b = c

Correct answer

B. a + b =- c

Step-by-step solution

Given that origin is orthocentre with slides of triangle are a , b , c array ll so, a + b + c 3 =0 & a + b + c =0 & array l By orthocentre = circumcentre for equilateral triangle array a + b =- c & array
