Sort the vectors from Q to each P i by angle of elevationdepression. Therefore To find we set them equal to one another and solve. In a parallelogram the two diagonals bisect each other at their centers.
To calculate the diagonal of a square multiply the length of the side by the square root of 2.
Type that value into the diagonal of a square calculator to check it yourself. In fact it is a 4-sided polygon just like a triangle is a 3-sided polygon a pentagon is a 5-sided polygon and so on. Let the diagonals intersect at a point b along the longer diagonal. Consider the Vertices Q65 and S3 2 of the diagonal QS.
