With Illustrator's Shape Tools, making a flawless triangle path can be easy. This tutorial will walk you through the processes to produce a neat, accurate triangular shape, whether you need one for a logo, icon, or other design component. The triangle can be readily modified to meet your needs using the Shape Tools and some fundamental skills. To understand how to make an ideal triangle path in Illustrator, refer to the tutorial below.
Step #1: Choose the Star Tool
Choose the Star tool from the Toolbar.
Step #2: Click Once on the Artboard
Click once on the artboard and the Star Tool Options pane will appear. This is where you can reduce the number of points to “3.” Set the radius of one triangle as 2, and then set the other radius at exactly half. Note: Radius 1 and 2 can be reversed as long as one is double/half the other. Pick the size of your triangle and click OK.
Step #3: Get Rid of the Extra Anchor Points
Choose the Subtract Anchor Point tool or hit the keyboard shortcut “-” (minus) to delete the 3 points that are in between the corners of your path.
You are done!
Now you have a perfect Triangle path.
You can do some experiments with the triangle like widen it, rotate it, etc.
