Use this interactive demo to learn how to create a rounded triangle shape in PowerPoint.

Quick summary

A rounded triangle in PowerPoint is created by inserting an Isosceles Triangle shape and using the Format Shape panel to apply a thick solid line with Round cap and join types, which softens the sharp corners into smooth curves.

Steps

Go to the Insert tab in PowerPoint.
Click Shapes located in the Illustrations group.
Select the triangle shape (Isosceles Triangle) from the shapes menu.
Draw the triangle shape on your slide.
Right-click the shape and select Format Shape from the context menu.
Click Line from the Format Shape tab.
Select Solid line as the line type.
Choose Round for both Cap type and Join type.
Adjust the Width until the triangle points turn into round corners.

📌 Why this matters

Creating a rounded triangle in PowerPoint is a valuable design skill for anyone building polished presentations, infographics, or slide decks. PowerPoint does not offer a native rounded triangle shape, so knowing this Format Shape workaround lets users produce smooth, professional-looking graphics without third-party tools. This technique gives presenters full control over corner radius by adjusting line width, making it easy to achieve custom, on-brand geometric shapes. Mastering this method saves time and elevates the visual quality of any PowerPoint presentation.
