There is no function to flip objects in PowerPoint 2002, but setting two objects can simulate the flip of an object.
For example, the real line triangle shown in Figure 1 is flipped along the right angle AB to the dotted line, and the vertex letter C moves as follows:
Figure 1
Draw a triangle with a text box labeled with vertex letters, text boxes C and triangles, and then copy the same shape, flip it horizontally and place it in the dotted line in Figure 1 (note: Do not let this object set to a dashed line). Right-click the first object, set a custom animation (Figure 2), use cascade in exit, direction to right, and the object shrink to the right to exit, with the start time "clicked", with no special requirements for speed.
Figure 2
Select the second object, set the custom animation (Figure 3), using "Stretch" in "enter", the direction is "from the left", the start time is after the previous item, and the second object extends immediately after the first object shrinks and exits, thus simulating an object's flip effect along one side with two objects. This method enables you to flip the horizontal or vertical four directions along the edge of the object.
Figure 3
If you want an object to flip around the vertical centerline axis, you should use two objects that are left and right to flip the relationship, aligning them to the center. The time relationship is the same as the previous one, except that the first object custom animation effect is "leap" when you exit, and the second object Custom animation effect extends when you enter, and jumps.
PowerPoint uses two objects to simulate objects flipping up and down along the horizontal center axis, you must use 4 objects to simulate an object's rollover effects along the horizontal center axis. In addition, the use of different sizes of colorless objects and visible objects to combine can simulate the object along any horizontal or vertical straight line of the effect, readers can be based on the previous said object flip to combine.
I have not found the use of PowerPoint to achieve the object in the direction of any oblique flip effect, which Master has a good method, I hope to share with you.
