Вопрос:

Как заполнить таблицы равных треугольников?

Ответ:

1. \( \triangle ABC \cong \triangle A_1B_1C_1 \): \( AB = A_1B_1 \), \( AC = A_1C_1 \), \( BC = B_1C_1 \), \( \angle BAC = \angle B_1A_1C_1 \), \( \angle BCA = \angle B_1C_1A_1 \), \( \angle ABC = \angle A_1B_1C_1 \). 2. \( \triangle DEF \cong \triangle D_1E_1F_1 \): \( ED = E_1D_1 \), \( EF = E_1F_1 \), \( DF = D_1F_1 \), \( \angle DEF = \angle D_1E_1F_1 \), \( \angle EDF = \angle E_1D_1F_1 \), \( \angle EFD = \angle E_1F_1D_1 \). 3. \( \triangle MLK \cong \triangle M_1L_1K_1 \): \( ML = M_1L_1 \), \( MK = M_1K_1 \), \( KL = K_1L_1 \), \( \angle MLK = \angle M_1L_1K_1 \), \( \angle MKL = \angle M_1K_1L_1 \), \( \angle KML = \angle K_1M_1L_1 \). 4. \( \triangle PTH \cong \triangle P_1T_1H_1 \): \( TH = T_1H_1 \), \( TP = T_1P_1 \), \( HP = H_1P_1 \), \( \angle PTH = \angle P_1T_1H_1 \), \( \angle TPH = \angle T_1P_1H_1 \), \( \angle PHT = \angle P_1H_1T_1 \). 5. \( \triangle SNQ \cong \triangle S_1N_1Q_1 \): \( SN = S_1N_1 \), \( QS = Q_1S_1 \), \( NQ = N_1Q_1 \), \( \angle SNQ = \angle S_1N_1Q_1 \), \( \angle NQS = \angle N_1Q_1S_1 \), \( \angle QSN = \angle Q_1S_1N_1 \).
