|Thales of Miletus geometry
Take the ends of the diameter of a circle, A and C, and consider any other point on the circle, B. then the triangle ABC is a right triangle. Consider the two isosceles triangles OAB and OBC. The base angles of an isosceles triangle are equal, and the three angles of a triangle add up to 180 degrees. Therefore, two α plus two β equals 180 degrees, so it is clear that α plus β equals 90 degrees, which is a right angle.
Solomon chose wisdom so he could be an adequate king, not knowledge of the number of moving spirits in heaven, nor whether a prime mover exists, nor whether a necessary conclusion can be drawn from a necessary premise and a contingent premise, nor whether a triangle can be constructed in a semicircle that does not have a right angle.
A point has no diameter, a line no width. A straight line has no deviation, a circle only one curvature. We do not assume these ideals; we do not pretend them. We say that any point, line, or circle drawn on wax or clay is only an approximation, only a crude representation. When our loved ones are with us, they can never be perfect. But true love is true, and can never deviate.
