Koeficient podobnosti úseček
Vypočítej koeficient podobnosti úseček, jestliže znáš:
\( \large\left|{CD}\right|=7cm,\left|{C^{\prime}D^{\prime}}\right|=4cm \)
\( \large k = \Large \frac{4}{7}\large \)
\( \large k = \Large \frac{5}{7}\large \)
\( \large k = \Large \frac{4}{5}\large \)
\( \large k = \Large \frac{7}{4}\large \)
