What are the characteristics of isoquant?

Isoquants are curves that represent combinations of two inputs, typically labor and capital, that yield the same level of output in production. They are downward sloping, indicating that as one input increases, the other must decrease to maintain the same output level. Isoquants do not intersect, as each curve corresponds to a different output level. Additionally, they are convex to the origin, reflecting the principle of diminishing marginal rates of technical substitution.
