Which statement about these two triangles is true

Answer:
Option A. is the correct option.
Step-by-step explanation:
By the theorem of similar triangles, when two triangles are similar their corresponding sides will be in the same ratio.
In ΔABC and ΔDEF
[tex]\frac{AB}{FD}=\frac{AC}{FE}=\frac{5}{10}=\frac{1}{2}[/tex]
So, these two triangles will be similar.
Option A. ΔABC and ΔDEF are similar because [tex]\frac{AB}{FD}=\frac{AC}{FE}[/tex]
