1. How do I resize an object in PowerPoint?

To resize an object in PowerPoint, follow these steps:

Step 1. Select the object you want to resize by clicking on it. Handles (small squares) will appear around the edges of the object.

Step 2. Hover your mouse over one of the handles until it turns into a double-headed arrow.

Step 3. Click and drag the handle inward or outward to resize the object. Dragging the handle outward will make the object larger, while dragging it inward will make it smaller.

Step 4. If you want to maintain the object's proportions while resizing, hold the Shift key on your keyboard while dragging the handle.

Step 5. Release the mouse button when you have achieved the desired size for the object.

That's it! You have successfully resized the object in PowerPoint.
