Where do two perpendicular line intersect?what is four-sided figure with one pair of parallel sides?

Because then it would be a parallelogram. Depending on how strictly you define it (two sides parallel or only two sides parallel), you could say that a parallelogram is a type of trapezoid.

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.
