Question

What is a plane in geometry

Answer 1

In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far. A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space. which would be the same in geo.

Answer 2

If we have three points such as points BCD, we can introduce an important figure in geometry which is called a plane.Think of a plane as a wall or the floor of a room or a flat surface that has no thickness.

To represent the idea of a plane, we can use a four-sided figure such as the one shown in the image provided. It's important to understand that a plane has no edges which means it extends forever in all directions. We can call the figure that is attached in the image provided plane BCD.
