在正方形网格中建立平面直角坐标系，点A、点B、点C分别在格点上，（1）在图1中，将△ABC向上平移2个单位，再向左平移1个单位长度，得到△A1B1C1，画出△A1B1C1；（2）在图2中，将△ABC平移，使点A的对应点为点O，点B的对应点为点B2，点C的对应点为点C2，画出△OB2C2，并直接写出△OB2C2的面积。---**Extraction Content:** **Figure 1:** * **Type:** Geometric figure (triangle) on a 2D Cartesian coordinate system. * **Coordinate System:** * X-axis: Horizontal axis, labeled 'x', marked from -4 to 5 with tick marks at integer values. Arrow points to the right. * Y-axis: Vertical axis, labeled 'y', marked from -2 to 5 with tick marks at integer values. Arrow points upwards. * Origin: Labeled 'O', at the intersection of the axes (0, 0). * **Elements:** * Point A: Located at coordinates (-2, -2). * Point B: Located at coordinates (3, 1). * Point C: Located at coordinates (0, 2). * Triangle ABC: Formed by connecting points A, B, and C with straight line segments. * **Label:** 图1 (Figure 1) **Figure 2:** * **Type:** Geometric figure (triangle) on a 2D Cartesian coordinate system. * **Coordinate System:** * X-axis: Horizontal axis, labeled 'x', marked from -4 to 5 with tick marks at integer values.
