**Q.1.** How will you describe the position of a table lamp on your study table to another person?

**Solution:**

** **To describe the position of a table lamp on the study table, we can take two mutually perpendicular sides of the table as X and Y axes. Take one corner of table as origin where both X and Y axes (sides) intersect each other. Drop two perpendiculars from this point on the two sides (i.e. X and Y axes). Measure the distance of the point from both X and Y axes and then write it in terms of coordinates, i.e. (x,y).
