Hi, Works for me. Draw an arrow A-B-C. Use the Close linestring tool and it comes a triangle with points A-B-C-A.

When you draw a triangle with LineString you will get an quadrangle when you close the linesegment. It is not so easy for me to teach new users why OJ can not catch the first point. But you posted some solutions I can teach. Thank you again.
