由文[1]易得:如图1,与椭圆ax22+yb22=1内接,且与圆x2+y2=aa22+bb22外切的多边形是菱形.笔者利用作图软件“超级画板”,经过探究,发现了一个类似的结论.定理与椭圆xa22+by22=1内接,且与圆x2+y2=(aa+bb)2外切的多边形是三角形.图1椭圆图2三角形图3三角形分析如图2,图3所示,若⊙O Easy to get from the text [1]: Figure 1, with the ellipse ax22 + yb22 = 1 inscribed, and with the circle x2 + y2 = aa22 + bb22 out of the polygon is a diamond. The author uses the mapping software “super drawing board”, after Explore, found a similar conclusion. Theorem and ellipse xa22 + by22 = 1 inscribed, and the circle x2 + y2 = (aa + bb) 2 out of the polygon is a triangle.
