Why is it important to take all three art theories into critiquing art?

It is important to take all three art theories into critiquing art because each theory offers a different perspective on the artwork. The formalist theory focuses on the formal elements of the artwork, such as line, shape, color, and texture. The expressive theory looks at the artwork from an emotional perspective, examining how the artwork conveys feelings and ideas. The contextual theory looks at the artwork in relation to its historical and cultural context, exploring how the artwork is shaped by its environment. By considering all three theories, one can gain a more comprehensive understanding of the artwork and its meaning.
