While it seems simple to think about how to make a triangle in Illustrator, but then you are left scratching your head asking yourself “Why isn’t there a triangle shape tool?”. I don’t know why they don’t have a tool for the shape when they have tools for Circles, Rectangles, Rounded Rectangles even stars!

In this complete guide, I’ll show you how to make a triangle in Illustrator.

How to Make a Triangle With the Polygon Tool in Illustrator

The simplest way to make a triangle in Illustrator is by using the polygon tool. 

To find the Polygon Tool click on the shape tool and hold it down so the drop-down appears with the various shape tools. Select the Polygon Tool that has a hexagon shape as the icon.

Draw the shape on your artboard at this point it will create a hexagon but don’t worry we can adjust the number of sides. Keep the shape selected and at the top of the menu bar click on the text ‘Shape’ this is where you’ll be able to change the number of sides on your polygon shape.

Set the number of sides to 3 and your shape will automatically turn into a triangle.

Just like that, you’ve learnt how to make a triangle in Illustrator. 

If you want to adjust the size of the triangle by making it longer or wider then keep reading and I’ll show you how.

How to Change The Size of the Triangle

Now that you’ve learnt how to make a triangle but you don’t want it to be an equilateral triangle. I’ll show how you can quickly scale the shape to make it longer or wider depending on your preference.

Select your triangle and using the bounding box that surrounds the shape you can proportionately scale the triangle to your liking.

Drag it either from the left or right side to make it wider. Drag it from the top or bottom to make it longer.

If you want to scale the triangle you can do so by holding down Shift on your keyboard and dragging one of the points on the bounding box.

How to Make a Rounded Triangle in Illustrator

When you have your shape selected using the cursor tool you’ll circle appear inside the triangle. Drag this circle down and you’ll be able to round the edge of the shape.

Feel free to adjust the radius of the shape by dragging it back and forth.

That’s it you’ve learnt everything you need to know about making a triangle in Illustrator.
