Here, $\triangle A'B'C'$ is the medial triangle. Here, $\triangle A'B'C'$ is the medial triangle.
The incircle of the medial triangle is called the \emph{Spieker circle} and the incenter is called the \emph{Spieker center}. The incircle of the medial triangle is called the \emph{Spieker circle} and the incenter is called the \emph{Spieker center}.
The circumcircle of the medial triangle is called the \emph{medial circle}. The circumcircle of the medial triangle is called the \emph{medial circle}.
An important property of the medial triangle is that the medial triangle $\triangle A'B'C'$ of the medial triangle $\triangle DEF$ of $\triangle ABC$ is similar to $\triangle ABC.$ An important property of the medial triangle is that the medial triangle $\triangle A'B'C'$ of the medial triangle $\triangle DEF$ of $\triangle ABC$ is similar to $\triangle ABC.$
