Final answer:
In triangle FGH, if FG is congruent to HF and the measure of angle F is 140 degrees, the measure of angle H is also 140 degrees.
Step-by-step explanation:
In triangle FGH, if FG is congruent to HF and the measure of angle F is 140 degrees, we can find the measure of angle H. Since FG is congruent to HF, this means that angle F is congruent to angle H. Therefore, the measure of angle H is also 140 degrees.
