摘要

给出了莫雷五圆定理的一个稍微扩展的代数证明。该定理适用于所有由可分离二次域扩展得到的密克尔平面Möbius，特别是经典实数平面Möbius。此外，这些计算还揭示了五圈定理的一个隐藏的孪生兄弟，这个孪生兄弟迄今为止似乎一直被忽视。

The Hidden Twin of Morley’s Five Circles Theorem

We give an algebraic proof of a slightly extended version of Morley’s Five Circles Theorem. The theorem holds in all Miquelian Möbius planes obtained from a separable quadratic field extension, in particular in the classical real Möbius plane. Moreover, the calculations bring to light a hidden twin of the Five Circles Theorem that seems to have been overlooked until now.
