Question

Select One

Answer 1

The missing reason in the proof you're working on is:

Transitive Property of Equality

This is the correct choice because, from statements 1 and 2, you establish that since \( m\angle A + m\angle C = 180^\circ \) and \( m\angle A = m\angle E \), you can substitute \( m\angle E \) for \( m\angle A \) in statement 1. Thus, leading to statement 3 which states \( m\angle E + m\angle C = 180^\circ \). This justifies the use of the Transitive Property of Equality for this proof.
