Answer with explanation:
Yes, it is a true statement ,that Cartesian coordinate system can have three dimensions .
There are many types of Cartesian coordinate system, some of them are
1. One Dimensional Cartesian coordinate system →→ Only a single number has to be represented.So, to represent this number you have to draw either a vertical or horizontal line,on which Positive and Negative real numbers are marked on that line.
2. Two Dimensional Cartesian coordinate system →→ An ordered pair, in the form of ,(x,y) has to be represented , with the help of two perpendicular lines,called X and Y axis.
3. Three Dimensional Cartesian coordinate system →→ A triplet is to be represented , that is ,(x,y,z) with the help of three mutually perpendicular lines, called ,x , y and z axes.
So, →→With the Reason Explained above, you can say with surety that, the Cartesian coordinate system can have three or more dimensions.
