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

Respuesta :

Answer:

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

Following are the response to the given equation:

Given:

[tex]\bold{ m \angle ABC=53^{\circ}}\\\\\bold{m \angle ECD=37^{\circ}}\\\\[/tex]

To find:

[tex]\bold{\Delta BAC \sim \Delta EDC=?}[/tex]

Solution:

[tex]\bold{\angle ABC=53^{\circ}}\\\\\bold{\angle ECD=37^{\circ}}\\\\[/tex]

If

 [tex]\to \bold{\angle ECD=37^{\circ}}\ \ \ \ \ \ \ \ \ \ then \ \ \ \ \ \ \ \ \ \bold{\angle CED=(90-37)^{\circ}= 53^{\circ}}\\\\[/tex]

therefore

[tex]\bold{\angle ABC =\angle CED }\\\\[/tex]

Yes, because the AA similarity postulate could be applied since a reflection over line f proves that [tex]\bold{\angle ABC \cong \angle DEC}[/tex] .
