Question

If the coordinate axes are not perpendicular to each other but two lines are at an angle of ${60}^{\circ }$. How many coordinates will be used to represent a point?

• A. 2
• B. 3
• C. 4
• D. 1

Answer 1

The correct option is A

2

The number of coordinates required will not change, as the points will be represented by the distance from the axes.
So even if the orientation of the axes is changed, each point will have two coordianates ( x , y ) representing the distance from each axis
Hence, we need 2 coordinates.
