Final answer:
The commonly found shape in man-made things that is easier to reproduce is geometric shapes.
Step-by-step explanation:
The shape commonly found in man-made things and easier to reproduce is geometric shapes. These shapes have clear and defined forms, making them easier to replicate. Examples of geometric shapes commonly used in man-made objects include squares, circles, and triangles.
For instance, in architecture, buildings often incorporate geometric shapes in their design, such as rectangular windows or triangular roofs. Similarly, in product design, objects like tables or chairs often feature geometric shapes for simplicity and ease of production.
Overall, geometric shapes are prevalent in man-made objects due to their defined forms and ease of reproduction.
