1 مثلث های هم نهشت را در شکل بیابید
و به زبان ریاضی بنویسید.
\(\begin{array}{l}ABC \cong JKL\\EDF \cong GHI\end{array}\)
2در شکل مقابل دو مثلث هم نهشت دیده میشود.
ضلع ها و زاویه های مساوی دو شکل را با علامت گذاری مشخص کنید. تساوی اجزای متناظر این دو مثلث را کامل کنید.
\(\begin{array}{l}\hat A = \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\overline {AB} = \\\hat B = \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = \,\,\,\\\hat C = \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = \end{array}\)
\(\begin{array}{l}\hat A = \,\hat D\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\overline {AB} = \overline {DE} \\\hat B = \,\hat E\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\overline {AC} \, = \,\overline {DF} \,\,\\\hat C = \,\,\hat F\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\overline {BC} \, = \,\overline {EF} \end{array}\)
