Which angle is congruent to ∠DFE?
An illustration shows two right angled triangle A B C and D E F; triangle A B C is larger than triangle D E F.
A.
∠ABC
B.
∠FDE
C.
∠FED
D.
∠ACB
The option D is correct. i.e., ∠ACB
In the given question is that
Which angle is congruent to ∠DFE
Answer is ∠DFE ~ ∠ACB
Explanation: By using the illustration shows two right angled triangle ABC and triangle DEF :
Now, If in triangles ABC and triangle DEF
Angle C = Angle F (Right angle)
CB = FE (leg)
AB = DE (hypotenuse)
then, triangle ABC is congruent to triangle DEF.
By SAS rule
Whole triangle ABC is congruent to triangle DEF. Then, we can say that
∠DFE ~ ∠ACB
Hence, The option D is correct. i.e., ∠ACB
