When a corner of square paper is folded, the crease is a line of symmetry. The folded triangle is congruent to the triangle it covers.
In a square, all corners are \(90^\circ\). Use the marked angles in the figure to find the folded angles, then use angles on a straight line (\(180^\circ\)) to find \( \angle MQN \) and \( \angle NRO \).
Final Answer: \( \angle MQN = 58^\circ \), \( \angle NRO = 122^\circ \)
