Question

what reason justifies saying al = be? cpcte reflexive transitive

Explanation:

CPCTE (Corresponding Parts of Congruent Triangles are Equal) is a principle used in geometry. If two triangles are congruent, then their corresponding sides and angles are equal. In this case, if the triangles (implied by the given markings) are congruent, then \(AL\) and \(BE\) (as corresponding parts) would be equal. The reflexive property states \(a = a\) (a side or angle is equal to itself). The transitive property states if \(a=b\) and \(b = c\), then \(a=c\). These do not justify \(AL = BE\) as well as CPCTE.

Answer:

CPCTE
