示例#1

文件： Rectangle.cs 项目： nice-nickname/FiguresDrawer_OOP

        private void FindParameters(out double height, out double width)
        {
            var pts = GetPoints();

            height = GeometryMath.FindMagnitude(new LineSegment(pts[0], pts[1]));
            width  = GeometryMath.FindMagnitude(new LineSegment(pts[1], pts[2]));
        }

示例#2

文件： Triangle.cs 项目： nice-nickname/FiguresDrawer_OOP

        public override bool IsExisting()
        {
            var lines = GetLines();

            var a = GeometryMath.FindMagnitude(lines[0]);
            var b = GeometryMath.FindMagnitude(lines[1]);
            var c = GeometryMath.FindMagnitude(lines[2]);

            return(a + b > c && a + c > b && b + c > a);
        }
