In a formal presentation, it is appropriate to use a formal greeting to show respect for the audience and set a professional tone.

Maintaining eye contact with individual audience members helps to engage them, show confidence, and create a connection.

In a formal presentation, it is generally considered polite to wait until the end to answer questions, allowing you to maintain the flow of your presentation and address all questions comprehensively.

Concluding a presentation with a brief summary of your main points helps to reinforce the key messages and leave a lasting impression on the audience.

Slides should be concise and easy to read, with two to three sentences per slide being the ideal length to convey key points effectively.

For presentation slides, a font size of 18-20 points is generally recommended to ensure that the text is large enough to be easily read by the audience.

Visuals can be a powerful tool to enhance your presentation by illustrating key points, making complex information more accessible, and capturing the audience's attention.

For most presentations, a duration of 20-25 minutes is considered ideal, allowing you to cover your main points effectively without overwhelming the audience.

In case of significant technical difficulties that disrupt the flow of your presentation, it is polite to apologize to the audience and offer to reschedule the presentation to ensure a smooth and successful delivery.

If you are unable to answer a question during your presentation, it is polite to acknowledge that you don't know the answer and promise to follow up with the information after the presentation, demonstrating your commitment to providing accurate and complete information.

In the event of hecklers or disruptive audience members, it is important to remain calm and respectful. Pause your presentation, address the situation directly, and request their cooperation in maintaining a respectful and productive environment for the presentation.

At the end of a presentation, it is customary to thank the audience for their time and attention, acknowledging their presence and engagement throughout the presentation.

After a presentation, it is considered good etiquette to send a thank-you note to the audience, share the presentation slides with them, and follow up with the audience members who asked questions, demonstrating your appreciation for their engagement and interest.
