1. If two planes intersect, then they intersect in a straight line.
2. If two lines intersect, they intersect at two different points.
3. β‘π΄π΅ and β‘π΅π΄ are the same line.
4. Three collinear points are coplanar.
5. Three coplanar points are collinear.
6. Any three points are coplanar.
7. If two rays share a common endpoint, then they form a line.
