Final answer:
The orderly design of Santa Maria Novella's facade by Leon Battista Alberti is achieved through symmetry, proportion, and repetition, but not asymmetry, which would contradict the harmonious qualities of Renaissance architecture.
Step-by-step explanation:
The facade of Santa Maria Novella in Florence, Italy designed by Leon Battista Alberti achieves its orderly design through the use of symmetry, proportion, and repetition. These are hallmark features of Renaissance architecture, which sought to revive the golden age of classical antiquity, emphasizing clarity, orderliness, and harmonic proportions. The option that does not contribute to the orderly design of the facade is asymmetry, as it implies a lack of balance and does not align with the characteristics of symmetry, proportion, or repetition.
