Teacher Contributed
Given that $\mathrm{△}ABC$$\triangle ABC$ ~ $\mathrm{△}DEF$$\triangle DEF$, the sides are proportional by $\frac{AB}{DE}=\frac{BC}{EF}$$\frac{AB}{DE} = \frac{BC}{EF}$, and the induded angle $\mathrm{\angle }$$\angle$B $\cong$$\cong$ $\mathrm{\angle }$$\angle$E, then the triangles are similar by SAS Similarity.
