Answer:
C) No, the triangles aren't congruent by SSS. ∠F ≅ ∠A, ≅ D)
Step-by-step explanation:
As we are not given one angle to work out whether they have the same sides or heights. What is presented that at least 2 adjacent angles are congruent within one triangle but due to one side measure not being present on each triangle we cannot determine and therefore do not have enough information to prove concurrency.
SSS means within one triangle.
This doesn't prove two are not congruent as it can also refer and speaks of one triangle using SSS. As C is precise to refer to 1 angles from each when making reference to not being congruent.
Therefore C is correct as it refers to height of the triangles using angle F and angle A which is the top of each triangle and the proof used if we had the side measure.
