Solution:
Given:
[tex]\begin{gathered} \angle S\cong\angle L................(given) \\ SA\cong AL..............(given) \end{gathered}[/tex]
[tex]\angle SAE\cong\angle LAG..................(vertically\text{ opposite angles are equal\rparen}[/tex]
Since two corresponding angles are equal in both triangles, then;
[tex]\Delta ESA\cong\Delta GLA[/tex]
