Question

What does $XY$ plane mean?

Answer 1

2D geometry $XY$ Plane:

• The $XY$ plane is a two-dimensional plane that helps to mark the position of a $2$-D object.
• The $x$-coordinate is called as abscissa and the $y$-coordinate is called as ordinate.
• The coordinate of a point is represented as $\left(x,y\right)$.
• The position of all points is determined with respect to the origin whose coordinates are $\left(0,0\right)$.

The axes divide the plane into four quadrants.

1. In the first quadrant, both $x$and the $y$values will be positive. All points will be of the form $\left(x,y\right)$.
2. In the second quadrant, $x$value is negative and the $y$value is positive. All points will be of the form $\left(-x,y\right)$.
3. In the third quadrant, both $x$and $y$values will be negative. All points will be of the form $\left(-x,-y\right)$.
4. In the fourth quadrant, $x$value will be positive and the $y$value will be negative. All points will be of the form $\left(x,-y\right)$.

Hence, the meaning of $XY$ Plane is explained.
