Question

If m∠ABC = 53° and m∠ECD = 37°, which statement explains whether the AA similarity postulate can be used to determine whether ΔBAC ~ ΔEDC?

Yes, the AA similarity postulate can be used because a reflection over line f will establish that ∠ABC ≅ ∠DEC.

Yes, the AA similarity postulate can be used because a reflection over line f will establish that segment AB ≅ segment DE.

No, the AA similarity postulate cannot be used because a reflection over line f will establish that ∠ABC and ∠DEC are not congruent.

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.
