1. The problem asks about the type of angles found in a square. 2. A square is defined as a quadrilateral with four equal sides. 3. By definition, all interior angles in a square are equal. 4. The sum of interior angles in any quadrilateral is $$360^\circ$$. 5. Since all four angles are equal in a square, each angle is $$\frac{360^\circ}{4} = 90^\circ$$. 6. An angle of $$90^\circ$$ is called a right angle. 7. Therefore, each angle in a square is a right angle.
