Euclidea 2.8 Solution Portable

The line connecting the intersection points of two circles is perpendicular to the line connecting their centers. In this specific configuration, the geometric properties ensure the resulting angle at 90 raised to the composed with power relative to the radius. math.stackexchange.com , 2.9 "Circle Tangent to Line"?

Given the confusion, let me give you the : euclidea 2.8 solution

Yes — check: Circle(O, OA) = original circle. Circle(A, AO) intersects original circle at A and X. AX is the common chord of the two equal circles. That chord is perpendicular to OA at A. So AX is tangent. Perfect. The line connecting the intersection points of two
