When designing layouts with Adobe InDesign, creating shapes such as triangles is a crucial skill.
This article will walk you through how to create a triangle by using the Pen Tool (also known as the Pen Tool), the Polygon Tool (also known as the Polygon Tool), and the Line Tool.
You will also receive some suggestions on how you can customize the triangle to suit your needs.
InDesign has a Pen Tool that is versatile and allows you create custom shapes. This includes triangles. Use the Pen Tool to create a triangular shape:
- Open your InDesign file or create a brand new one.
- The Tools panel is located on the left-hand side of the screen. You can also press the “P” key to activate the Pen Tool.
- Create the anchor point of your triangle by clicking on the canvas.
- Click twice to create your second anchor. Then click once more to make the third anchor.
- Click the first anchor you created. This will close your shape. Fill the triangle with the color you have selected.

It is easy to use the Polygon Tool to create polygons, including triangles. Here’s how to create a triangle using the Polygon Tool:
- Open your InDesign file or create a brand new one.
- You can find it by clicking and holding the Rectangle Tool, then selecting the Polygon Tool on the Tools panel. Click and hold the Rectangle Tool, then select the Polygon Tool in the dropdown menu.
- Click and hold on the canvas, and then press the “Up Arrow” or “Down Arrow” key on your keyboard to change the number of sides of the polygon. Adjust the number until you get a triangular shape (3 sides).
- Release the mouse button and the triangle will appear on the canvas.
The Line Tool can be used to draw the sides of a triangle. To create a triangle with the Line Tool, follow these steps:
- Open your InDesign file or create a brand new one.
- Select the Line Tool from the Tools panel, or press the backslash (“”) key on your keyboard.
- Drag the canvas and click to create the first triangle side.
- Click and drag from the ends of the previous lines to create the second and third side, creating a closed form.
- Select all three lines using the Selection Tool, and then go to the “Object” menu > “Paths” > “Join” to merge the lines into a single closed shape, creating your triangle.
Customizing Your Triangle
You can modify the appearance of your triangle by changing its fill colour, stroke color, or stroke width. You can do this by using the Swatches panel or Stroke panel.
You can also rotate and scale your triangle
If you want to adjust the size or rotation of your triangle after creating it, follow these steps: Follow these steps:
- Use the Selection Tool (V) to select the triangle.
- Click and hold the corner handles of the triangle’s bounding box. You will see a double-headed arrow that allows you to rotate the triangular. Drag the mouse to move the triangle in the desired direction.
- Holding the Shift Key will allow you to maintain the aspect-ratio while dragging the corner handles. You can scale the triangle in a non-uniform way by dragging the handles while holding the Shift Key.
- Release the mouse to apply the transformation.
Applying effects to Your Triangle
InDesign provides a variety of effects you can apply to your triangular object to enhance its appearance. Follow these steps to apply an effect:
- Use the Selection Tool (V) to select the triangle.
- Go to the “Object” menu > “Effects” and choose an effect, such as Drop Shadow, Bevel and Emboss, or Gradient Feather.
- Adjust the settings in the Effect dialog box to get the desired effect.
- Click “OK” to apply the effect to your triangle.

Clipping paths and text wrapping
You can also use it as a path for masking an image. Or you can wrap text around your triangle. Here’s how:
Create a Clipping Path
- Place an image in your InDesign document using the “File” menu > “Place” or by dragging and dropping the image from your file explorer.
- Hold the Shift Key while selecting both the triangle as well as the image with the Selection Tool (V).
- Go to the “Object” menu > “Clipping Path” > “Make.” The image will now be clipped within the triangle shape.
Applying Text Wrapping
- Use the Selection Tool (V) to select the triangle.
- Open the Text Wrap panel by going to the “Window” menu > “Text Wrap.”
- Select a text wrap style from the panel, such as “Wrap Around Object Shape” or “Jump Object.”
- Set the offset value and adjust the distance to the text.
The conclusion of the article is:
Mastering the techniques of creating, transforming and applying effects to triangles within InDesign will take your skills to a new level. Create visually striking layouts by combining triangles with other design elements.
