Answer:
The answer to your question is below
Step-by-step explanation:
Data
D (0, b)
E (a, b)
F(a, 0)
G (0, 0)
From this information, we conclude that the diagonals are EG and DF.
To prove that they are congruent we must calculate their length.
dEG =
dEG =
dDF =
dDF =
Conclusion
The length of EG is equal to the length of DF, so they are congruent.
