I have been trying to make an isoceles triangle according to directions I found on the web.

1Use Square/Rectangle tool to make a Square
2. convert object to pathe (Path/Object to path)
3.Use Edit Node Tool
4. select one corner (diamond shape turns red
5 "delete" the corner to create a triangle


Everything is easy until the last step. When I click on "delete" the whole square disapears.

What am I doing wrong?
Thanks.

Welcome to InkscapeForum!

Hhhm, it seems to me that this process will create a right triangle. Isn't an isoceles triangle equal lengths on 2 sides? Although I think it's possible to have a triangle which is both right and isoceles.

Well ok, to answer your question -- when you're on step 3, when you hover your mouse over the node (tiny gray triangle) it turns red. Then you have to click it to select it. After you move your mouse away, it will change to and remain blue. That's when you know you've successfully selected it, and Delete will delete only that selected node. But after you delete it, I suspect you will see something like this:



If you do want a right triangle, then next, still with the Node tool, hover your mouse over each tiny circle (these are node handles), and Ctrl + click. Then you will have a perfect right triangle.



If you want to draw an isoceles triangle, I would suggest using a grid, snapping, and the Pen tool. Here are the steps:

1 - Enable a grid (View menu > grid) (You can actually customize the grid quite a bit, but I suspect the default grid will work well here.)
2 - Enable snapping: on the snap toolbar, click the top button to engage snapping (or far left button, depending on your version and/or setup) , deselect "Snap bounding box corners", select "Snap nodes or handles" and "Snap to grids".
3 - Engage the Pen tool
4 - Click on the 3 corners to create the triangle, as shown below:



The grid allows you to make the 2 equals sides exactly equal. And snapping causes the Pen to deposit a node exactly at the grid intersections. After you finish, if you see that the nodes aren't in the right places, you can simply drag them to the right grid intersection to fix it. So all together, you can get a technically perfect isoceles triangle You could use the same method to get a perfect right triangle, of course. But since you were following some other instructions, I answered those questions first.

Let us know if you have any further questions

Thank you very much that worked !

If a square is created first (not a rectangle) then this process creates a triangle that is a right triangle with two equal sides

I had a person with a degree in graphics who is pretty good in Illustrater, looking over my shoulder and she couldn't figure out what was going wrong.

The web directions said "delete the node to remove the corner". It said *nothing about it being a * 2 step process

I'm creating a system for my students with autism to make objects out of triangles, small rectangles, small square, based on a 1 1/2" square so that everything can fit together, so I prefer the method of basing everything on the "master square" rather than drawing the other shapes with lines - although of course it would work.

Again thanks - this was making me crazy.
