Homework Equations
let the point where the line through B and X intersects with AC be P
The Attempt at a Solution
[/B]
I know that
ACdotBP = 0
AC = AD+DC
BP = PC+ CD
Therefore (AD+DC)dot(PC+CD)=0
I also know that:
ECdotCE = 0
BCdotDA=0
However I am stuck on showing that the dot product of ACdotBP is equal to 0
If anyone can help me it would be much appreciated
thanks
