<section id="description">考虑所有三角形:格点上的所有顶点。原点O. Orthocentre在圆点H(5,0)处的圆环。有九个这样的三角形,其周长≤50。按周长的升序列出并显示,它们是: <p> A(-4,3),B(5,0),C(4,-3)A(4,3),B(5,0),C(-4,-3)A(-3,4) ),B(5,0),C(3,-4)A(3,4),B(5,0),C(-3,-4)A(0,5),B(5,0) ),C(0,-5)A(1,8),B(8,-1),C(-4,-7)A(8,1),B(1,-8),C( - 4,7)A(2,9),B(9,-2),C(-6,-7)A(9,2),B(2,-9),C(-6,7) </p><p>他们的周长总和,四舍五入到小数点后四位,是291.0089。 </p><p>查找周长≤105的所有此类三角形。输入其周长的总和四舍五入到小数点后四位。 </p></section>
