Now that you're set, let's learn how to make a triangle in Adobe Illustrator.

2. How to Make a Triangle in Illustrator

Triangle drawing in Illustrator is quite simple. Let's start with the most basic method. Select the Pen Tool (P) from your toolbar and create your triangle with three simple clicks.

Holding down the Shift key while drawing the lines will create perfectly straight lines, making it a lot easier to create a 90-degree angle in Illustrator.

3. How to Make a Right Triangle in Illustrator

Select the Rectangle Tool (M) and create a rectangle or a square. Hold down the Shift key while dragging to easily create a perfect square.

Switch to the Direct Selection Tool (A), select one of those anchor points, and remove it using the Remove Selected Anchor Point button from the control panel.

Alternatively, you can use the Delete Anchor Point Tool (-) to simply click the anchor point that you want to be removed.

4. How to Make a Perfect Triangle in Illustrator

Select the Polygon Tool and just click on your artboard. Make sure that you enter 3 in the Sides input box, set the size of the triangle that you are about to create, and click OK.

Because the Polygon Tool is built to create shapes with equal angles at their corners, you will end up with an equilateral triangle.
