Answer:
△ABC∼△DFE
Explanation:
The order of the triangle is ABC as you can see in the angles ABC angle A has 3 lines, angle B has one and angle C has two, you have to match those with the similar angles of the second triangle, Angle D has 3, angle F has 1, and angle E has 2, So A is conected to the B and then to the C, in consequence the second triangle D is conected to F and then to E so the correct option would be:
△ABC∼△DFE
