Question

How will you describe the position of a table lamp on your study table to another person

Answer 1

To describe the position of a table lamp on the study table, we have two take two lines, a perpendicular and horizontal.

Considering the table as a plane and taking the perpendicular line as $Y$ axis and horizontal as $X$ axis.

Take one corner of the table as origin where both $X$ and $Y$axes intersect each other.

Now, the length of the table is $Y$ axis and breadth is $X$axis.

From the origin, join the line to the lamp and mark a point.

Calculate the distance of this point from both $X$ and $Y$ axes and then write it in terms of coordinates.
Let the distance of a point from $X$ axis is $x$ and from $Y$ axis is $y$ then the position of the table lamp in terms of coordinates is $(x,y).$
