MCQ
In three dimensions, the coordinate axes of a rectangular cartesian coordinate system are:
  • A
    Three mutually parallel lines
  • B
    Three mutually perpendicular lines
  • C
    Two mutually perpendicular lines and any two parallel
  • D
    None of these
✓

Answer

  1. Three mutually perpendicular lines

Solution:

In three dimensions, the coordinate axes, i.e. x, y and z axes of a rectangular cartesian coordinate system are three mutually perpendicular lines. The word rectangular is used to indicate perpendicularity among the axes.
