平移是图形变换的一种,在日常生活中有着广泛的运用.不仅如此,图形还可以在平面直角坐标系中进行平移变换,下面举例说明.一、点的平移例1将点P(1,2)向左平移1个单位长度,再向下平移2个单位长度后得到的对应点的坐标是__.解析:向左平移1个单位长度,横坐标减
Translation is a kind of graphic transformation, which has a wide range of applications in daily life.Furthermore, graphics can also be transformed in plane Cartesian coordinate system, as an example.A translation example of a point P (1, 2) Shift to the left by 1 unit length, and then shift down 2 units length to get the corresponding point coordinate is __. Analysis: Shift to the left by 1 unit length, abscissa minus
