Question

the ratio, approximately equal to 1.618, is often found in nature and used in design for aesthetically pleasing compositions.
a sequence is a pattern where each number is the sum of the two preceding ones, beginning with 0 and 1.
and proportion in design refers to the balance and harmony between different parts of an artwork or structure, often using the golden ratio.
drawing techniques are employed to create the illusion of depth on a flat surface, using horizon lines and vanishing points.
a is a pattern made of shapes that repeat without any gaps or overlaps, demonstrating the power of geometry in creating complex designs.

Explanation:

1. The Golden Ratio (approximately 1.618) is a well - known mathematical concept with applications in design.
2. The Fibonacci sequence follows the rule \(F_n = F_{n - 1}+F_{n - 2}\) (\(F_0 = 0,F_1 = 1\)).
3. The concept of unity in design relates to balance and harmony, often incorporating the Golden Ratio.
4. Perspective drawing techniques use geometric principles (horizon lines, vanishing points) to create depth.
5. A tessellation is a geometric pattern of non - overlapping, non - gap - creating repeated shapes.

Answer:

1. Golden
2. Fibonacci
3. Unity
4. Perspective
5. tessellation
