🗑
unique line postulate   through any 2 points there is exactly 1 line  
🗑
unique plane postulate   through any 3 noncollinear points there is exactly 1 plane  
🗑
unique postulate 1   if 2 distinct points lie in a plane, then the line joining them also lies in that plane  
🗑
unique postulate 2   if 2 distinct lines intersect, then their intersection is a point  
🗑
unique postulate 3   if 2 distinct planes intersect, then their intersection is a line-it may look like a segment but it goes on forever just like the planes  
🗑
