When a corner of rectangular paper is folded, the crease acts as a line of symmetry. The folded portion is congruent to its original position.<br><br>
The angle at the corner of a rectangle is \(90^\circ\). After folding, angles are transferred. Use the marked angles in the figure and angle sum properties to find \( \angle AEB \).<br><br>
\( \angle AEB = 128^\circ \).<br><br>
Final Answer: 128&deg;
