点A(-2,1,4),点A关于原点对称点坐标是:
A: (1,-2,-4)
B: (-2,1,-4)
C: (2,-1,-4)
D: (2,1,-4)
A: (1,-2,-4)
B: (-2,1,-4)
C: (2,-1,-4)
D: (2,1,-4)
举一反三
- 已知点(2,1),则它关于原点的对称点坐标为() A: (1,2) B: (2,-1) C: (-2,1) D: (-2,-1)
- 点M(﹣2,1)关于y轴的对称点N的坐标是() A: (2,1) B: (1,﹣2) C: (﹣2,﹣1) D: (2,﹣1)
- 点\( P(2, - 1,3) \) 关于 \( xOy \)坐标面,关于\( x \) 轴,关于原点的对称点分别为( ). A: \( (2, - 1, - 3),(2,1, - 3),( - 2,1, - 3) \) B: \( ( - 2, - 1, - 3),(2, - 1, - 3),( - 2,1, - 3) \) C: \( (2, - 1, - 3),( - 2,1, - 3),( - 2, - 1, - 3) \) D: \( ( - 2, - 1, - 3),( - 2,1, - 3),(2, - 1, - 3) \)
- 点M(3,-2,1)关于坐标原点的对称点是( ) A: (-3,2,-1) B: (-3,-2,-1) C: (3,-2,-1) D: (-3,2,1)
- 点M(3,-2,1)关于坐标原点的对称点是( ) A: (-3,2,-1) B: (-3,-2,-1) C: (3,-2,-1) D: (-3,2,1)
