Need help rounding corners on triangle

I’ve seen numerous comments and instructions regarding Boolean functions but I can’t get the desired effect I’m looking for. I’m looking to round the pointed corners of a triangle. I added a circle and intersected it towards the tip of the triangle, clicked on the triangle to highlight it, held down shift and clicked on the circle. I selected Boolean subtract and these are the options I get. It’s my understanding that the blue lines indicate what the fininshed figure should look like but as you can see that is not what I get. What am I doing wrong?

There are two tools for this:

  • Corner Tool

OK

and

  • Fillet All:

OK

If you still have difficulties, upload the file.

Great! Thanks for your help.
