If you plan it right, you can choose the exact moments to add impact to your presentation just by switching from the REST position to the POWER position from any of the three places in the Presenter’s Triangle™.
For example, let’s say you have 20 minutes to present. You decide to start off in the middle of the triangle in the “rest” position (at a 45-degree angle to the room). On a particularly busy visual, you decide to move to the back of the triangle, closer to the screen, but still in your rest position. Then, from that same spot, you choose to square off into a “power” position just long enough to emphasize a key point. A moment later, you revert to the rest position, again, as you continue to present your information.
Perhaps later during your presentation you decide to move to the front of the triangle, and you get a little closer to the crowd, still in a rest position. As you tell of an experience related to the topic — at the high point in the story — you square off to the audience for impact.
The point of all this is that you planned some of the action. You don’t have to plan a move for EVERY spoken word! But, certain moments can be critical in your talk and you can create a plan for how your body will support the effort of your well-chosen words. If you can get used to being a “visual” presenter, the positions of the triangle and the angles of the body will be additional tools available for you to create impact.
