\begin{definicja}[{\cite[str.~71]{Doman}}]
Niech dany będzie zbiór $k$ punktów na płaszczyźnie, tzn. $\mathcal{K}_0=\{P_1, P_2, \ldots, P_k\}$. Kreśląc wszystkie możliwe okręgi i proste z danych punktów oraz wyznaczając ich części wspólne otrzymamy nowe punkty $P_{k+1}, P_{k+2}, \ldots, P_{k+l}$, gdzie $l \in \mathbb{N}$. \\
Zbiór złożony z punktów $P_1, P_2, \ldots, P_k$ oraz z punktów $P_{k+1}, P_{k+2}, \ldots, P_{k+l}$ nazywa się zbiorem punktów konstruowalnych i oznacza się go jako $\mathcal{K}_1$.

我添加了手动定义的定理样式，如下所示：
\newtheoremstyle{bfnote}% name of the style to be used.
{9pt}% measure of space to leave above the theorem.
{9pt}% measure of space to leave below the theorem.
{}% name of font to use in the body of the theorem.
{}% measure of space to indent.
{\bfseries}% name of head font.
{\\}% punctuation between head and body.
{0.5em}% space after theorem head; " " = normal interword space.
{\thmname{#1}\thmnumber{ #2}\thmnote{ #3}}% manually specify head.
