Perpendicular Lines

Theorems:

In a plane, through a point on a line there is exactly one line perpendicular to the line

Through a point not on a line, there is exactly one line perpendicular to the line.

The book shows some constructions -- look at these similar ones online:

• Given point P on line k, construct a line through P, perpendicular to k.
• Given point R, not on line k, construct a line through R, perpendicular to k.
