Ответ:
The correct option is ΔABC ≅ ΔFED by SAS
Step-by-step explanation:
Looking at the given diagram,
Side AC = Side DF = 3.2
Side AB = Side FE = 4 units
Angle A = angle F = 72 degrees
Since two sides and one angle are equal, then triangle FED = triangle ABC by SAS(side angle side)
This makes the ratios possible
AB/FE = AC/DF
The HL given means hypotenuse leg. It will not hold because the triangles are not right angle triangles.
