One way was to measure land. Since land was measured in square units, they needed some way to measure parts of land along the Nile. They would use a rope with 12 equally spaced knots it it and make a Pythagorean 3-4-5 right triangle.
This would give them a right angle and a proper measurement.
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.
