How to Make a Triangle in Illustrator? However, for beginners, this can be a real problem, since the figure “triangle” is not in the standard tools of Adobe Illustrator.
Method 1.
Select the Pen tool (the [P] key) and click in three places in the workspace to get a triangular shape and a fourth time in the first point to close the outline. You can also close the path by selecting three points and pressing [Ctrl+J].
Method two.
Select the Line Segment tool (key [\]) and draw three straight lines so that the end of the previous line coincides with the beginning of the next line (the end of the third line should coincide with the beginning of the first line). Select the resulting lines and press [Ctrl+J] to close the contour.
Method three.
Select the Rectangle tool (press [M] key) and draw a rectangle. Then select the Delete Anchor Point tool (the [-] key) and click one of the rectangle corner points to delete it.
Method four.
Select the Polygon tool from the same menu as the Rectangle tool. Click on the workspace and without releasing the left mouse button, you can press the up and down arrows on the keyboard to adjust the number of corners of the polygon.
Method five.
Select the Star tool from the same menu as Polygon. Click on the workspace and, without releasing the left mouse button, you can press the up and down arrows on your keyboard to adjust the number of the star ends.
