In the standard \((x, y)\) coordinate plane, line \(m\) is the reflection of line \(l\) across the \(x\)-axis. If the intersection of lines \(l\) and \(m\) is the point \((r,s)\), which of the following must be true? () A. \(r=0\) B. \(s=0\) C. \(...
解析 A。长方形的四个顶点坐标分别为(1,1)、(1,3)、(3,1)、(3,3)。两点间的水平距离或垂直距离可以通过对应坐标相减得到。这里计算长方形的长或宽,比如水平方向上两点(1,1)和(3,1),横坐标之差为 3 - 1 = 2,所以长方形的一条边长为 2。
