List and briefly explain any three Principles of Flexibility that support usability.

Principle of Equivalence: This principle states that the system should provide equivalent alternatives to ensure accessibility and usability. For example, providing text descriptions for non-text content such as images or videos can help users with visual impairments understand the content.

Principle of Flexibility in Use: This principle emphasizes that the design should accommodate a wide range of individual preferences and abilities. This could mean providing different ways of interacting with the system, such as using a mouse, keyboard, or voice commands.

Principle of Simple and Intuitive Use: This principle suggests that the design should be easy to understand, regardless of the user's experience, knowledge, language skills, or current concentration level. This could mean using familiar concepts, minimizing the complexity of the interface, and providing effective prompting and feedback during and after task completion.
