点M(2, 1, 3)关于坐标原点的对称点坐标是()
A: (-2, -1, -3)
B: (-2, 1, -3)
C: (2, -1, -3)
D: (-2, 1, 3)
A: (-2, -1, -3)
B: (-2, 1, -3)
C: (2, -1, -3)
D: (-2, 1, 3)
举一反三
- 点(1, 2, 3)关于坐标原点O对称的点的坐标为( ) A: (-1, -2, -3) B: (-1, -2, 3) C: (1, 2, -3) D: (1, 2, 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)
- 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(2,-3,1)关于坐标原点对称的点是( ) A: (-2,3,-1) B: (-2,-3,-1) C: (2,-3,-1) D: (-2,3,1)
