How many minimum points are required to draw unique line in plane
Hint 1: Recall the postulate: 'Through any two distinct points, there is exactly one straight line.'
Hint 2: How many points do you need to pin down a line so it cannot rotate?
Hint 3: Recall that while a single point allows infinitely many lines to rotate around it, adding a second distinct point pins the line's direction down completely, leaving exactly one unique straight line passing through both.
Step 1 (Geometric Axiom): According to the fundamental axioms of Euclidean geometry, a unique straight line can be drawn through any two distinct points in a plane.
Step 2 (Analyze minimum points):
point is not enough, as infinitely many lines can pass through a single point.
distinct points uniquely define exactly line.
Step 3 (Conclusion): The minimum number of points required is exactly 2.
