Question

if triangle RST is congruent to triangle ABC under corrospondence RST <-> write all the corresponding congruent parts of the triangles

Answer 1

$$\begin{gathered} \mathrm{If}\mathrm{triangle}\mathrm{RST}\mathrm{is}\mathrm{congruent}\mathrm{with}\mathrm{triangle}\mathrm{ABC}\mathrm{then}\mathrm{under} \\ △\mathrm{RST}\cong △\mathrm{ABC} \\ \mathrm{we}\mathrm{can}\mathrm{say}\mathrm{that}, \\ \angle \mathrm{R}=\angle \mathrm{A} \\ \angle \mathrm{S}=\angle \mathrm{B} \\ \angle \mathrm{T}=\angle \mathrm{C} \\ \mathrm{and}\mathrm{RS}=\mathrm{AB} \\ \mathrm{RT}=\mathrm{AC} \\ \mathrm{ST}=\mathrm{BC} \\ \mathrm{Also}\mathrm{area}\mathrm{of}\mathrm{triangle}\mathrm{RST}=\mathrm{Area}\mathrm{of}\mathrm{triangle}\mathrm{ABC} \end{gathered}$$
