Best ResponseYou've already chosen the best response.2that means you add up the x coordinates and divide by 2 dw:1439083618310:dw

Best ResponseYou've already chosen the best response.2I added the x coordinates 0 and 2a to get 2a then I divided 2a by 2 to get 'a'

Best ResponseYou've already chosen the best response.2the same idea is applied to find Q and R

Best ResponseYou've already chosen the best response.2for the other stuff, you use the distance formula \[\Large d = \sqrt{\left(x_{2}x_{1}\right)^2+\left(y_{2}y_{1}\right)^2}\]

Best ResponseYou've already chosen the best response.0so we need Q and R hmmm Q is (3a/2,b/2) R is (a/2, b/2)

Best ResponseYou've already chosen the best response.0if Q ( 3a/2, b/2) then there are points that can lead us to this. if R ( a/2,b/2) then there are points that lead to this result points A and C may lead us to R

Best ResponseYou've already chosen the best response.0\[\Large d = \sqrt{\left(x_{2}x_{1}\right)^2+\left(y_{2}y_{1}\right)^2} \] \[\Large d = \sqrt{(0\frac{3a}{2})^2+(0\frac{b}{2})^2} \] \[\Large d = \sqrt{(\frac{3a}{2})^2+(\frac{b}{2})^2} \] \[\Large d = \sqrt{(\frac{9a^2}{4})+\frac{b^2}{4}} \] if we let \[\large b = a \sqrt{3} \] \[\Large d = \sqrt{(\frac{9a^2}{4})+\frac{(a \sqrt{3})^2}{4}} \] \[\Large d = \sqrt{(\frac{9a^2}{4})+\frac{(3a^2)}{4}} \] \[\Large d = \sqrt{\frac{12a^2}{4}}\] \[\Large d = \sqrt{3a^2} \] \[\Large d = a\sqrt{3} \] Now do the same process for RB for R ( a/2,b/2) and B (2a,0)
