## Description
|
|||
|
<section id="description">考虑点(x,y)的集合Ir,其中半径为r的圆内部的整数坐标以原点为中心,即x2 + y2 <r2。对于半径为2,I2包含九个点(0,0),(1,0),(1,1),(0,1),( - 1,1),( - 1,0),( -1,-1),(0,-1)和(1,-1)。在I2中有八个三角形具有全部三个顶点,其中包含内部的原点。其中两个如下所示,其他通过旋转从这些中获得。 <p>对于半径为3,有360个三角形包含内部的原点并且所有顶点都在I3中,而对于I5,该数字是10600。 </p><p>有多少个三角形包含内部的原点并且在I105中包含所有三个顶点? </p></section>
