#GIS folks, (maybe #CAD too) how do you draw this kind of shape with guaranteed perfectly tangent lines and only 4 vertices?

I've been trying different things for 3-4 years on and off and the closest I've come is 5 vertices, ESRI leaves a spare vertex in there for some reason and so I don't know which one I delete will ruin the tangent

This is not a need, it's a mental chalenge
