Looking at the given diagram, angle AEC and angle DEB share the same vertex, E. They are described as vertically opposit angles. In geometry, vertically opposite angles are equal. This means that
Angle DEB = angl AEC = 50 degrees
Since all reflections are inverse of itself, carrying any reflection about the same axis twice will carry the preimage back to itself.
