For any triangle T in the xy-coordinate plane, the centerof T is defined to be the point whose x-coordinate is the average (arithmeticmean) of the x-coordinates of the vertices of T and whose y-coordinate is theaverage of the y-coordinates of the vertices of T. If a certain triangle has vertices 顶点at the points(0,0) and (6,0) and center at the point (3,2), what are the coordinates of theremaining vertex?这个题意思我都没有看懂啊,那个神人给我翻译下,并解答下啊。谢谢了 |
