Sufficient properties are characteristics or features that, when present, ensure that a particular object or concept belongs to a specific category or fulfills a certain condition. For example, in mathematics, a sufficient property might be a condition that guarantees a triangle is classified as an equilateral triangle if all three sides are equal in length. In logic and philosophy, sufficient properties help in defining concepts clearly. They provide criteria that must be met for something to be considered a member of a group. For instance, having wings and the ability to fly are sufficient properties for classifying an animal as a bird.
