Can I please get some help would very much appreciate it

The Solution:
Given:
We are required to compare the three (3) triangles based on the similarity property in the above diagram.
The three triangles are:
[tex]\begin{gathered} \Delta MKL \\ \Delta MLN \\ \Delta LKN \end{gathered}[/tex]So, the similarity of the 3 triangles is expressed as below:
[tex]\Delta KML\cong\Delta KLN\cong\Delta LMN[/tex]Therefore, the correct answer is [option 4]
