A half-circle or semi-circle is a useful design element in PowerPoint presentations. It can be used for diagrams, infographics, and creative visual elements. This guide will walk you through the simple steps to create a half-circle in PowerPoint using built-in shape tools and formatting options.
How to Create a Semi Circle in PowerPoint
There are different methods for creating a semi-circle or half-circle in PowerPoint, including using a Partial Circle shape or merging two shapes together. For the purpose of this post, we will add a semi-circle to a slide in the Data Science Shapes PowerPoint Template.
Method 1: Create Semi Circle Using a Partial Circle Shape
To create a semi-circle using the Partial Circle shape edit method, follow the below-mentioned process.
Step 1: Open the slide to which you want to add the semi-circle and insert a partial circle shape via Insert -> Shapes.

Step 2: Click on the circle to select it and adjust the yellow handles to form a perfect semi-circle. You can move the yellow lines to create a half-circle shape that best suits your needs. This method can be used to create circles with different variations of a semi-circle or a partial piece of a circle (e.g., showing one-fourth of a circle).

Method 2: Create Semi Circle Using Merge Shapes
Step 1: Open PowerPoint and navigate to the slide where you want to add the half-circle. Click on Insert -> Shapes and add an oval shape, followed by a rectangle shape on top of it.

Step 2: Go to Shape Format -> Merge Shapes -> Intersect. This will remove one-half of the circle, leaving a precise semi-circle.

Customizing the Half Circle Created in PowerPoint
Different options in PowerPoint can be used to customize the half-circle shape.
1. Change the Fill and Outline: To change the fill and outline to give the half-circle a custom look, click on the half-circle to select it, and go to Shape Fill to change the color. Use Shape Outline to adjust the border thickness or remove it entirely.
2. Rotate the Half Circle: Click on the shape and use the Rotate option to position it as needed.
3. Apply Effects for Better Visibility: Use Shape Effects like shadow or glow to make the half-circle stand out. Adjust transparency for layering effects.
4. Align and Distribute for Consistency: Use Align tools to position the half-circle precisely on your slide. If using multiple semi-circles, distribute them evenly for a professional look.

Bonus Tip: Use the Half Circle in Diagrams
Half-circle diagrams can add great value to your slides. You can create such diagrams by Combining them with text, icons, or other shapes for visually appealing slides. Using multiple half-circles to create pie charts, progress indicators, or creative layouts. Half circles can represent different stages in a process, making them useful for flowcharts and business infographics. They can act as visual dividers in a presentation, breaking up content into easy-to-present sections.
