How many least number of distinct points determine a unique plane?

Explanation

To determine a unique plane in Euclidean geometry, we need to follow these steps:

1. **Understanding the Concept of a Plane**: A plane is a flat, two-dimensional surface that extends infinitely in all directions. In Euclidean geometry, a plane can be defined by points.

2. **Identifying Points**: We need to consider how many distinct points are required to define a unique plane. A single point does not define a plane, as it can lie anywhere in space.

3. **Using Two Points**: When we take two distinct points, we can draw a straight line connecting them. However, this line does not define a unique plane because there are infinitely many planes that can contain this line.
