怎么解答这一题？---**Problem Type:** 操作题 (Operation problem) **Points:** (2+2+2=6 分) (2+2+2=6 points) **Image Description:** * **Type:** Grid with coordinate axes and geometric shapes. * **Grid:** A grid marked with dashed lines. * **Coordinate Axes:** X-axis labeled from 0 to 14, Y-axis labeled from 0 to 5. * **Shapes:** * Four connected squares located at coordinates: (1,2), (2,2), (1,3), and (2,3). * A triangle labeled ABC. * Point A is at (5,3). * Point B is at (5,1). * Point C is at (7,1). **Textual Content:** 1. 左面已经涂了4个方格，请你再涂一个方格，使得5个方格组成的图形是轴对称图形，并画出它的对称轴。 (Left side has already colored 4 squares, please color one more square so that the figure formed by the 5 squares is an axis-symmetric figure, and draw its axis of symmetry.) 2. 把三角形 ABC 绕点 A 逆时针旋转 90°, 画出旋转后的图形。 (Rotate triangle ABC counterclockwise by 90° around point A, and draw the rotated figure.) 3. 把三角形 ABC 旋转后的图形向右平移 4 格，再向下平移 2 格，画出平移后的图形。 (Translate the rotated figure of triangle ABC 4 units to the right, and then 2 units down, and draw the translated figure.)
