Answer:
Yes, the AA similarity postulate can be used because a reflection over line f will establish that ∠ABC ≅ ∠DEC.
Explanation:
Generally from the question we are told that
m∠ABC = 53°
m∠ECD = 37°
Generally from the diagram we see that
m∠BAC = 90°
and
m∠EDC = 90°
So
m∠DEC = 90- 37 °
=> m∠DEC = 53 °
Since m∠DEC = m∠ABC then
Yes, the AA similarity postulate can be used because a reflection over line f will establish that ∠ABC ≅ ∠DEC.
