Step 1: Understanding Design Shapes.
Squares, triangles, and circles are common geometric shapes used in design work due to their symmetry and visual appeal. An angle, however, is not a shape but a measurement between two lines and is less suitable as a standalone design element.
Step 2: Verifying the Options.
- Option (1): Squares are commonly used in design due to their symmetry.
- Option (2): Triangles are also frequently used in design for their stability.
- Option (3): Circles are widely used in design for their balance.
- Option (4): Angles are not shapes but measurements, making them unsuitable for design work.
Conclusion:
Therefore, the correct answer is (4) Angle.
