一、填空题1.已知点A(-3,2),则点A关于x轴的对称点A1的坐标为,点A关于y轴的对称点A2的坐标为,点A关于原点的对称点A3的图1坐标为.2.如图1,△ABC为等边三角形,若AB=2,则B、C、A三点坐标分别为:B,C,A.3.已知点P(2,-3),将P点向右平移2个单位长度,再将P点的纵坐标乘-1得另一点P′, First, fill in the blank problem 1. Known point A (-3, 2), then point A on the x axis of the symmetry point A1 coordinates, point A on the y axis of symmetry point A2 coordinates, point A on the origin of the symmetry The coordinate of Fig. 1 of point A3 is .2. As shown in Fig. 1, △ABC is an equilateral triangle. If AB=2, the coordinates of B, C, and A are respectively: B, C, A.3. Known point P (2, -3), P point is shifted 2 units to the right, then the ordinate of point P is multiplied by -1 to get another P’,
