A postulate is a statement that is taken to be true without proof to support the reasoning process in the development of a theorem or a proof.
Examples
A few well-known postulates from Euclidean geometry are listed here:
- One and only one straight line can be drawn through any two points.
- If two points lie in a plane, then the line joining the two points lies in the same plane.
- The shortest distance between any two points is a straight line.
