Euler 9 point circle

    [SOLVED] Euler 9 point circle

    I'm doing a project on the nine point circle and i need to know what type of triangle it works with. I tried constructing it but it didn't work with an isoscoles or a obtuse triangle, but a website said it works with all triangles, can anyone help?

    it works with any triangle.

    what happened when you tried to construct it with an isosceles triangle? it should have worked, why didn t it?

    It does work with an isosceles triangle but not with an obtuse because the altitude is outside of the triangle. I'm trying to find a good website that explains it's history and what it's used for today.
