Solution:

Given two triangles;

Triangle ABC and DEF are similar only if;

$\begin{gathered} \angle A\cong\angle D \\ \angle B\cong\angle E \\ \angle C\cong\angle F \end{gathered}$

Thus, we have;

$\begin{gathered} \angle A=180^o-80^o-60^o \\ \angle A=40^o=\angle D \end{gathered}$

Also,

$\angle B=\angle E=80^o$

Also,

$\begin{gathered} \angle F=180^o-80^o-40^o \\ \angle F=60^o=\angle C \end{gathered}$

FINAL ANSWER: Triangle ABC and DEF are similar triangles
