Where are the right angles on the arc de triomphe?

Each of the four pillars has a rectangular shape at ground level. There you could find a square angle (vertical side of the pillar + horizontal surface of the ground), and a square angle at each turn of every pillar. At the top of the arc you'll find another horizontal surface which is at a square angle with the vertical sides, plus four square angles at the turn of every side.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
