|---|---|---|---|---|---|
| If a line is perpendicular to each of two intersecting lines at their point of intersection, then the line is perpendicular to the plane determined by them |
🗑
|

| Through a given point there passes one and only one plane perpendicular to a given line |
🗑
|
||||
| Though a given point there passes one and only one line perpendicular to a given plane |
🗑
|
||||
| Two lines perpendicular to the same plane are coplanar, because the lines are parallel |
🗑
|
||||
| Two planes are perpendicular to each other if and only if one plane contains a line perpendicular to the second plane |
🗑
|
||||
| if a line is perpendicular to a plane, then any line perpendicular to the given line at its point of intersection with the given plane is in the given plane |
🗑
|
||||
| if a plane intersects two parallel planes, then the intersection is two parallel lines |
🗑
|
||||
| If two planes are perpendicular to the same line, they are parallel |
🗑
|
||||
| if a line is perpendicular to a plane, then every plane containing the line is perpendicular to the given plane |
