- 1). Open the PowerPoint presentation and select the slide, from the list of slides on the left, where you want to add you text. If the slide already contains text or object boxes that you will not need, click on the and press "Del" to remove them.
- 2). Click on the "Insert" tab at the top of the screen. Locate the "Text" area and select the "WordArt" button. Choose how you want your text to look from the list of styles that appear. Once you click on a style, a box will appear on the PowerPoint slide containing the words "your text here."
- 3). Click inside the text box. Use the "Backspace" and "Del" keys to remove the text and then type in the words you want to form in a half circle.
- 4). Select the "Format" tab at the top of the screen and then click on the "Text Effects" button in the "WordArt Styles" area. Move your mouse over "Transform" to open up a small window containing a number of text effects. Choose the "Arch Up," "Chevron Up," "Deflate" or "Deflate Bottom" option to shape the text into a half circle. Each of those four options will have a slightly look, so try each one until you find one that works best with the size and length of your text.
