图形与坐标包括平面直角坐标系、确定物体的位置、图形变换后点的坐标的变化三部分内容.它借助平面直角坐标系,揭示了坐标平面内的点与一对有序实数之间的一一对应关系,对称点的坐标特征、图形的变换前后点的坐标的变化规律.一、中考内容要求1.在直角坐标系中,会根据坐标描出点的位置、由点的位置写出它的坐标.
The figure and coordinates include the plane rectangular coordinate system, the position of the object, and the change of the coordinates of the point after the graphic transformation. It is based on the Cartesian coordinate system and reveals that a point between a coordinate plane and a pair of ordered real numbers A correspondence between the symmetry point of the coordinate characteristics of the graphics before and after the transformation point changes in the coordinates of I. First, the exam content requirements 1 in the Cartesian coordinate system, according to the coordinates of the location of the plot point from the point of writing its position coordinate.
