While in high school, plain old Euclidian geometry used to drive me crazy. After taking a course in Riemiannian and Lobacheviskian geometry in college, Euclidian geometry started to look easy. After all, everybody knows the Pythagorean Theorem. Here is what will turn out to be a very simple high school level geometry problem. This is a circle below is divided into four equal quadrants. A right triangle, the kind used for the Pythagorean Theorem, is inscribed in one of the quadrants. You are given the hypotenuse of the triangle and a line segment between the circle and the triangle. What is the radius?
Now add the radius times .016 to the north coordinates and add the radius times .020 to the west coordinates. It is just that easy.
