How did African masks achieve formal balance in their design?

O use of symmetry
O use of color
O use of texture
O use of natural materials

African masks achieved formal balance in their design through the following elements:

1. Use of Symmetry: African masks often employ symmetrical designs to create a sense of balance. The mask's features, such as eyes, nose, and mouth, are often repeated on both sides of the mask, creating a symmetrical composition.

2. Use of Color: The careful use of color in African masks also plays a role in achieving formal balance. Colors are strategically selected and applied to create a harmonious and balanced visual effect. The use of contrasting colors or complementary color schemes can help achieve balance in the overall design.

3. Use of Texture: African masks often incorporate various textures to create depth and visual interest. Textures can be achieved through different materials such as wood, clay, or fibers. The careful application of texture helps to achieve formal balance by adding visual weight to different areas of the mask's design.

4. Use of Natural Materials: African masks are typically crafted from natural materials found in their surroundings, such as wood, clay, leaves, feathers, or shells. The use of these materials, which often have inherent organic shapes and patterns, contributes to achieving formal balance in the design by working with the natural characteristics of the materials.

Overall, the combination of symmetry, color, texture, and the use of natural materials contributes to achieving formal balance in African masks' design.
