Solution :
\[\overrightarrow{A}.\overrightarrow{B}=\overrightarrow{A}.\overrightarrow{C}\] \[\Rightarrow \] \[\overrightarrow{A}.\overrightarrow{B}-\overrightarrow{A}.\overrightarrow{C}=0\] \[\Rightarrow \] \[\overrightarrow{A}(\overrightarrow{B}-\overrightarrow{C})=0\] \[\Rightarrow \] \[\overrightarrow{A}\bot (\overrightarrow{B}-\overrightarrow{C})\]You need to login to perform this action.
