WebBy using the converse of Pythagoras' theorem, it suffices to show that OP2 + MP2 = OM2. We have that OP2 = OA ⋅ OA ′ = (OB − AB)(OB + AB) = OB2 − AB2 = (OM2 − MB2) − AB2 = OM2 − (MB2 + AB2) = OM2 − MA2 = OM2 − MP2. Hence, any circle through a point A and its inverted point A ′ is perpendicular to the inversion circle. WebMar 7, 2024 · So the circumference of circle R would be: c = 2 π r c = 2 π 4 c = 8 π But, since we only have half a circle, we must divide that number in half. 8 π 2 = 4 π c = 4 π Now, we can do the same for circle S. But we …
