A square has its centre at the origin and sides parallel to the axes. One vertex is at (4, 4).
What are the coordinates of the vertex diagonally opposite to it?

Class 9Plotting PointsCoordinate Geometry
  • A(-4, -4)
  • B(4, -4)
  • C(-4, 4)
  • D(0, 0)

Step-by-Step Solution

The diagonal passes through the centre (origin), so the opposite vertex is the origin-reflection of (4, 4), i.e. (-4, -4).
Answer: A) (-4, -4)
