The vertex B of square OABC with each side 4 units lies in the fourth quadrant and its side are along the co-ordinate axes. The co-ordinate of vertex B are (4, -4). Co-ordinate Geometry, Concise Mathematics Solutions ICSE Class 9.

Vertex B lies in the fourth quadrant. The square's sides are along the coordinate axes, so one vertex, O, is at the origin (0, 0).

The side length is 4 units.

With O at (0, 0), the other two vertices on the axes must be A (4, 0) on the positive x-axis and C (0, -4) on the negative y-axis.

The fourth quadrant is where the x-coordinates are positive and the y-coordinates are negative.

Vertex B is located at the point where the line extending 4 units to the right from C (0, -4) intersects with the line extending 4 units down from A (4, 0), which is (4, -4).

⇒ B = (4, –4).

∴ Statement 1 is true, and statement 2 is false.

Hence, option 3 is the correct option.
