Answer
\[\Delta ABC\]and\[\Delta ADE\]are similar because \[\overleftrightarrow{ED}\text{ and }\overleftrightarrow{CB}\text{ are parallel}\].
Work Step by Step
\[\Delta ABC\]and\[\Delta ADE\]are similar because it is given that the line ED and CB are parallel. Since, the line DA and BA are in the same line.
It is concluded that the measure of angle B and angle D is same.
